Sobolev Gradients and Differential Equations
ISBN: 9783642040405 / Angielski / Miękka / 2009 / 312 str. Termin realizacji zamówienia: ok. 20 dni roboczych. A Sobolev gradient of a real-valued functional on a Hilbert space is a gradient of that functional taken relative to an underlying Sobolev norm. This book shows how descent methods using such gradients allow a unified treatment of a wide variety of problems in differential equations. For discrete versions of partial differential equations, corresponding Sobolev gradients are seen to be vastly more efficient than ordinary gradients. In fact, descent methods with these gradients generally scale linearly with the number of grid points, in sharp contrast with the use of ordinary gradients....

A Sequence of Problems on Semigroups
ISBN: 9781461430063 / Angielski / Miękka / 2013 / 142 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This text consists of a sequence of problems which develop a variety of aspects in the field of semigroupsof operators. Many of the problems are not found easily in other books. Written in the Socratic/Moore method, this is a problem book without the answers presented. To get the most out of the content requires high motivation from the reader to work out the exercises. The reader is given the opportunity to discover important developments of the subject and to quickly arrive at the point of independent research. The compactness of the volume and the reputation of the author lends this... This text consists of a sequence of problems which develop a variety of aspects in the field of semigroupsof operators.

Difference Matrices for Ode and Pde: A Matlab(r) Companion
ISBN: 9783031119996 / Angielski / Miękka / 2023 / 204 str. Termin realizacji zamówienia: ok. 20 dni roboczych. The use of difference matrices and high-level MATLAB® commands to implement finite difference algorithms is pedagogically novel. This unique and concise textbook gives the reader easy access and a general ability to use first and second difference matrices to set up and solve linear and nonlinear systems in MATLAB which approximate ordinary and partial differential equations. Prerequisites include a knowledge of basic calculus, linear algebra, and ordinary differential equations. Some knowledge of partial differential equations is a plus though the text may easily serve as a supplement for...
