Krzysztof Kowalski – författare

The book studies how multiple representations of the Other are constructed, Europeanized and used in Poland and Sweden in various heritage related contexts (museums, cities, war cemeteries, commemoration sites etc.) in the second decade of the 21st century. In a more general sense, the authors raise the question of how otherness (in terms of culture, ethnicity, class, gender, etc.) is constructed and leads to its social inclusion, domestication, marginalization or – increasingly common in Scandinavian and Central European peripheries – exclusion.

This book is the first monograph on a new powerful method discovered by the author for the study of nonlinear dynamical systems relying on reduction of nonlinear differential equations to the linear abstract Schrödinger-like equation in Hilbert space. Besides the possibility of unification of many apparently completely different techniques, the “quantal” Hilbert space formalism introduced enables new original methods to be discovered for solving nonlinear problems arising in investigation of ordinary and partial differential equations as well as difference equations. Applications covered in the book include symmetries and first integrals, linearization transformations, Bäcklund transformations, stroboscopic maps, functional equations involving the case of Feigenbaum-Cvitanovic renormalization equations and chaos.
