Download or read book Fractional Volterra Integral Equations: A Neural Network Approach written by Antonio Luciano Martire and published by Roma TrE-Press. This book was released on 2022-12-24 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Il Calcolo Frazionario ha recentemente guadagnato un crescente interesse nella letteratura economica e finanziaria. Per quanto riguarda i modelli economici, quelli di crescita sono stati modellati utilizzando una rappresentazione tramite derivate frazionarie. Questo tipo di equazioni non consente soluzioni in forma chiusa e quindi è necessario ricorrere a metodi numerici appropriati per ottenere approssimazioni accurate delle soluzioni. Per questo motivo, in questo contributo, proponiamo un approccio basato sulle cosiddette Physics Informed Neural Network per risolvere le equazioni integrali di Volterra di ordine frazionario. Alcuni esperimenti numerici mostrano l’accuratezza dell’algoritmo suggerito.

Book Synopsis Volterra Integral Equations by : Hermann Brunner
Download or read book Volterra Integral Equations written by Hermann Brunner and published by Cambridge University Press. This book was released on 2017-01-20 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive introduction to the theory of linear and nonlinear Volterra integral equations (VIEs), ranging from Volterra's fundamental contributions and the resulting classical theory to more recent developments that include Volterra functional integral equations with various kinds of delays, VIEs with highly oscillatory kernels, and VIEs with non-compact operators. It will act as a 'stepping stone' to the literature on the advanced theory of VIEs, bringing the reader to the current state of the art in the theory. Each chapter contains a large number of exercises, extending from routine problems illustrating or complementing the theory to challenging open research problems. The increasingly important role of VIEs in the mathematical modelling of phenomena where memory effects play a key role is illustrated with some 30 concrete examples, and the notes at the end of each chapter feature complementary references as a guide to further reading.
Book Synopsis Fuzzy Fractional Differential Operators and Equations by : Tofigh Allahviranloo
Download or read book Fuzzy Fractional Differential Operators and Equations written by Tofigh Allahviranloo and published by Springer Nature. This book was released on 2020-06-15 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains new and useful materials concerning fuzzy fractional differential and integral operators and their relationship. As the title of the book suggests, the fuzzy subject matter is one of the most important tools discussed. Therefore, it begins by providing a brief but important and new description of fuzzy sets and the computational calculus they require. Fuzzy fractals and fractional operators have a broad range of applications in the engineering, medical and economic sciences. Although these operators have been addressed briefly in previous papers, this book represents the first comprehensive collection of all relevant explanations. Most of the real problems in the biological and engineering sciences involve dynamic models, which are defined by fuzzy fractional operators in the form of fuzzy fractional initial value problems. Another important goal of this book is to solve these systems and analyze their solutions both theoretically and numerically. Given the content covered, the book will benefit all researchers and students in the mathematical and computer sciences, but also the engineering sciences.

Book Synopsis A risk-gain-sparsity optimization approach by : Alessandra Congedo
Download or read book A risk-gain-sparsity optimization approach written by Alessandra Congedo and published by Roma TrE-Press. This book was released on 2024-06-12 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uno dei principi fondamentali dei modelli di selezione del portafoglio è la minimizzazione del rischio attraverso la diversificazione degli investimenti. Tuttavia, i benefici della diversificazione si riducono in presenza di un'elevata correlazione tra gli asset. È noto che la diversificazione attraverso l'uso di portafogli più ampi non è il modo migliore per ottenere un miglioramento della performance fuori campione. Inoltre, l'inclusione di un numero elevato di posizioni nel portafoglio aumenta i costi di gestione e di transazione. Mentre i modelli classici di selezione del portafoglio si concentrano sulla minimizzazione del rischio e sulla massimizzazione del rendimento, lo scopo di questo lavoro è quello di includere un terzo obiettivo: la norma-1. Ciò consente di selezionare portafogli sparsi, cioè con un numero limitato di attività, che sono più facili da gestire e consentono di ottenere buoni risultati in termini di rischio-rendimento. La nostra analisi empirica si basa su un dataset di riferimento disponibile pubblicamente e spesso utilizzato in letteratura. DOI: 10.13134/979-12-5977-332-6
Book Synopsis Portfolio selection using behavioral models by : Andrea Gheno
Download or read book Portfolio selection using behavioral models written by Andrea Gheno and published by Roma TrE-Press. This book was released on 2023-10-16 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nell'ambito dei problemi di scelta in condizioni di rischio introduciamo un nuovo modello comportamentale e implementiamo un'analisi empirica basata sul confronto con il classico approccio della Teoria del Prospetto. L'applicazione di questi modelli è validata nella selezione di portafoglio attraverso tre modelli di portafoglio tradizionali utilizzati come riferimento (portafoglio a varianza minima, portafoglio a deviazione mediana assoluta e portafoglio equamente ponderato). L'obiettivo di questo lavoro di ricerca è quello di incorporare la percezione del rischio degli investitori nelle scelte dei portafogli ottimali. Proponiamo un'analisi out-of-sample di quattro indici azionari per dimostrare la superiorità dei modelli comportamentali di selezione di portafoglio rispetto a quelli tradizionali.

Book Synopsis Artificial Neural Networks for Engineers and Scientists by : S. Chakraverty
Download or read book Artificial Neural Networks for Engineers and Scientists written by S. Chakraverty and published by CRC Press. This book was released on 2017-07-20 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential equations play a vital role in the fields of engineering and science. Problems in engineering and science can be modeled using ordinary or partial differential equations. Analytical solutions of differential equations may not be obtained easily, so numerical methods have been developed to handle them. Machine intelligence methods, such as Artificial Neural Networks (ANN), are being used to solve differential equations, and these methods are presented in Artificial Neural Networks for Engineers and Scientists: Solving Ordinary Differential Equations. This book shows how computation of differential equation becomes faster once the ANN model is properly developed and applied.

After an introduction to the theory of Volterra equations and to numerical integration, the book covers linear methods and Runge-Kutta methods, collocation methods based on polynomial spline functions, stability of numerical methods, and it surveys computer programs for Volterra integral and integro-differential equations.
Book Synopsis The value of cultural clashes in M&A by : Francesco Saverio Stentella Lopes
Download or read book The value of cultural clashes in M&A written by Francesco Saverio Stentella Lopes and published by Roma TrE-Press. This book was released on 2023-12-22 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Il presente lavoro esamina il ruolo della cultura aziendale nelle fusioni e acquisizioni, sia in termini di probabilità di essere coinvolti in un’operazione, sia in termini di esito della stessa. Lo studio dimostra che una cultura aziendale orientata verso l’esterno, quindi attenta alla creazione di valore per gli azionisti e al rapporto con i competitor, aumenta significativamente la probabilità di partecipare ad operazioni di M&A, ma ha un impatto negativo sulla loro capacità di generare valore. Tale evidenza viene confermata tramite l’utilizzo di un esperimento naturale che considera uno shock esogeno alla cultura aziendale, proveniente dall’approvazione di diverse leggi sul congedo parentale negli Stati Uniti. I nostri risultati suggeriscono che le aziende orientate all'esterno sottovalutano la possibilità di scontri culturali dopo una fusione e hanno maggiori probabilità di concludere accordi che distruggono valore.
