Considering the phenomenon of the mean reversion and the different speeds of stock prices in the bull market and in the bear market, we propose four dynamic models each of which is represented by a parameterized ordinary differential equation in this study. We solve the models by dynamic integration and apply them to the daily closing prices of the Taiwan stock index, Taiwan Stock Exchange Capitalization Weighted Stock Index. The empirical study shows that some of the models fit the prices well and the forecasting ability of the best model is acceptable even though the martingale forecasts the prices slightly better. To increase the forecasting ability and to broaden the scope of applications of the dynamic models, we will model the coefficients of the dynamic models in the future. Applying the models to the market without the price limit is also our future work. Stock indices draw a lot of attention in the financial field and modelling stock prices is one of the major topics.

Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It only takes a minute to sign up. I am working on my thesis which is about oscillations and as far as I realise I need to know about perturbation theory and methods in solving differential equations, specifically dynamical systems. A Googling returned the following results:. Does anybody have any suggestion? First one seems reasonable but I am not sure about the quality.

The basic concepts necessary to study differential equations - critical points and equilibrium, periodic solutions, invariant sets and invariant manifolds - are discussed. Stability theory is developed starting with linearisation methods going back to Lyapunov and Poincare.

Part of the Universitext book series UTX. He graduated at the University of Amsterdam in Astrophysics and Mathematics. A period of five years at the Technological University of Delft, started his interest in technological problems, resulting in various cooperations with engineers. His other interests include the methods and applications of asymptotic analysis, nonlinear oscillations and wave theory. He holds a chair of dynamical systems at the department of mathematics at the University of Utrecht. Among his other interests are a publishing company, Epsilon Uitgaven, that he founded in , and the relation between dynamical systems and psychoanalysis.

Announcements and other information about the class can be found here. Course description. The focus of this course is bifurcation theory and averaging methods for nonlinear dynamical systems, including infinite-dimensional dynamical systems and partial differential equations. Topics covered include the Lyapunov-Schmidt reduction, Leray-Schauder degree-theoretic methods, some of the local and global bifurcation results due to Crandall, Rabinowitz, Krasnoselski, and Dancer, the Hopf bifurcation, center manifolds and normal forms, and geometric approaches to averaging theory. Several topics from functional analysis, such as Fredholm operators and spectral theory for bounded operators, will be covered in class to facilitate the understanding of the above material.

 Мы его не украли, - искренне удивилась Росио.  - Человек умирал, и у него было одно желание. Мы просто исполнили его последнюю волю. Беккер смягчился. В конце концов, Росио права, он сам, наверное, поступил бы точно так .

Бросив быстрый взгляд на кабинет Стратмора, он убедился, что шторы по-прежнему задернуты. Сьюзан Флетчер минуту назад прошествовала в туалет, поэтому она ему тоже не помеха. Единственной проблемой оставался Хейл. Чатрукьян посмотрел на комнату Третьего узла - не следит ли за ним криптограф.

У испанцев всегда было иное представление о плотности, чем у остального мира. Беккер оказался зажат между двумя полными женщинами с закрытыми глазами, предоставившими толпе нести их в собор. Они беззвучно молились, перебирая пальцами четки.

Кошачья жила. Из нее делают струны для ракеток. - Как мило, - вздохнула. - Итак, твой диагноз? - потребовал. Сьюзан на минуту задумалась.

 Увы, - сказал Нуматака, которому уже наскучило играть, - мы оба знаем, что Танкадо этого так не оставит. Подумайте о юридических последствиях. Звонивший выдержал зловещую паузу. - А что, если мистер Танкадо перестанет быть фактором, который следует принимать во внимание. Нуматака чуть не расхохотался, но в голосе звонившего слышалась подозрительная решимость.

 En que puedo servile, senor. Чем могу служить, сеньор? - Он говорил нарочито шепеляво, а глаза его внимательно осматривали лицо и фигуру Беккера. Беккер ответил по-испански: - Мне нужно поговорить с Мануэлем. Загорелое лицо консьержа расплылось еще шире.

 Keine Ursache. Беккер вышел в коридор. Нет проблем. А как же проваливай и умри. ГЛАВА 36 Ручное отключение.
