Description of  Difference Equations in Normed Spaces: Stability and Oscillations (ISSN Book 206)

B000W10GYW pdf Difference equations appear as natural descriptions of observed evolution phenomena because most measurements of time evolving variables are discrete. They also appear in the applications of discretization methods for differential, integral and integro-differential equations. The application of the theory of difference equations is rapidly increasing to various fields, such as numerical analysis, control theory, finite mathematics, and computer sciences. This book is devoted to linear and nonlinear difference equations in a normed space. The main methodology presented in this book is based on a combined use of recent norm estimates for operator-valued functions with the following methods and results:The freezing methodThe freezing methodThe Liapunov type equationThe Liapunov type equationThe method of majorantsThe method of majorantsThe multiplicative representation of solutionsThe multiplicative representation of solutionsDeals systematically with difference equations in normed spaces Deals systematically with difference equations in normed spaces Considers new classes of equations that could not be studied in the frameworks of ordinary and partial difference equationsConsiders new classes of equations that could not be studied in the frameworks of ordinary and partial difference equationsDevelops the freezing method and presents recent results on Volterra discrete equationsDevelops the freezing method and presents recent results on Volterra discrete equationsContains an approach based on the estimates for norms of operator functionsContains an approach based on the estimates for norms of operator functions
