Singularities in some variational problems
ISBN: 9783639175158 / Angielski / Miękka / 260 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The book is concerned with the analysis of singularities that appear in several variational problems. These singularities play the role of vortex lines for superconductors, vortices in Bose-Einstein condensates or domain walls in micromagnetics. Their study requires a good understanding of maps with values into the unit circle. The first part of the book treats the question of lifting of maps of bounded variation with values into the unit circle, together with the analysis of their topological singularities. In the second part, we study the vortex structure of a rotating Bose-Einstein...

Analytische Methoden und die Black-Scholes-Modelle
ISBN: 9783639370768 / Niemiecki / Miękka / 240 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In den vergangenen Jahren haben stochastische Modelle bei der Modellierung von Aktienkursen zunehmend an Bedeutung gewonnen. Das Buch beschaftigt sich mit stochastischen Volatilitatsmodellen. Diese stellen eine unmittelbare Verallgemeinerung der gewohnlichen Black-Scholes-Modelle dar, mit dem Unterschied, dass die Volatilitat nun nicht mehr als konstant sondern als stochastisch angenommen wird. Dabei wird ein Hauptaugenmerk auf eine mathematisch exakte und verstandliche Herleitung dieser Modelle gelegt. Weiterhin wird der Zusammenhang zwischen Optionspreisbestimmung und partiellen...

Nonlocal Functional Evolution Equations
ISBN: 9783838347417 / Angielski / Miękka / 232 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Our research work is mainly based on applicability of rich theory of functional analysis to analyze the existence, uniqueness and continuous dependence on initial data of the solutions of the evolution equations of integral and fractional orders with non-local conditions. Our work can be divided into four major parts: In the first part, we consider the non-local evolution equations of integral order and having operators with dense domain. Because of operators having dense domain, we use the theory of semi- group for our analysis. In the second part, we focus our attention on evolution...

Variational Convex Analysis
ISBN: 9783838372747 / Angielski / Miękka / 264 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work develops duality for systems originally modeled by non-linear differential equations. For such problems, the variational formulations are in general non-convex. In many situations the primal approaches have no solutions in the classical sense, being the minimizing sequences only weakly convergent. However, through the dual formulations, it is possible to compute these weak limits, and such evaluations have many practical applications, such as for composites in elasticity, phase transition models, problems in micro-magnetism, and others. Among such results in variational analysis, we...

Research for developing price forecasting tools in deregulated markets is at an intermediate stage. Researchers have developed various forecasting models covering most of the deregulated markets. The researchers have paid more attention towards price forecasting in day-ahead electricity markets as compared to real-time electricity markets; whereas, price forecasting in real time electricity markets is difficult as compared to day-ahead electricity markets. Short term price forecasting (STPF) is a complex task because price series is highly volatile with non-constant mean and variance, which...
