Linear Time-Invariant Systems, Behaviors and Modules

ULRICH OBERST is Professor Emeritus at the University of Innsbruck, Austria. Earlier, he was professor of mathematics at the same university from 1972-2009. He completed his Ph.D. in Mathematics from the University of Munich, Germany, in 1965, under the guidance of Prof. F. Kasch who, in particular, taught injective co-generators-a notion from homological algebra which plays an important part in the present book. He has visited a number of universities in several countries on invitations, including Pennsylvania State University, USA, University of California San Diego, USA, University of Chicago, USA, University of Florida, USA, and University of Rome II, Italy. His areas of interest include algebra and applied mathematics with special emphasis on constructive methods, in particular multidimensional linear systems theory and discrete Gelfand, Fourier and Hartley transforms. A father of two and grandfather of six, Prof. Oberst is happily married to Karla. He is also an experienced piano player and has participated in two chamber music ensembles, playing piano trios, quartets and quintets with, in particular, string players from the Tyrolean Symphony Orchestra Innsbruck.

"This 700-plus page book provides a multifaceted introduction to linear time-invariant (LTI) systems theory, both for continuous-time and discrete-time. ... In my view, this book is interesting and can be helpful to students and researchers interested in LTI systems theory." (Jin Liang, zbMATH 1478.93003, 2022)
