Dr. Horst Beyer's lecture notes "Beyond partial differential equations. On linear and quasi-linear abstract hyperbolic evolution equations"
[Lecture Notes in Mathematics 1898. Berlin: Springer (2007)] was included in the sixteen highlights selected by the editors of Zentralblatt MATH for 2008. Dr. Beyer's work is the outgrowth of a two-semester course on linear semigroup methods, linear and quasi-linear hyperbolic systems of partial differential equations, and the abstract theory of evolution equations, given at Louisiana State University in Baton Rouge.
