Title: Gravitational ji.t'ld of gyratons on various background spacetrm.es Author: Hcdvika Kadlecovd Department: Institute of Theoretical Ph.ys-i.es Supervisor: doc. Pavel Krtous. Ph.D. Supervisor's e-mail address: Pavel.Krtou.s({hnff.rum.cz Abstract: In this work we have, found, and, analyzed, several gyraton solutions on various non-trivial backgrounds in the large. Kundt class of spacet'imes. Namely, the gyraton solutions on direct product spacctiincs, ayraton solutions on Melvin universe and its generalization which includes the cosmological constant. These, solutions are. of algebraic type II. Also me have investigated, type III solutions within the Kundt class and we have found the. gyratons on de Sitter spacctiw.e. We have, generalized, the gyraton solutions on direct product spacetimes to higher dimensions.

Algebraic classification of the Weyl tensor : selected applications
Pravda, Vojtěch
Selected applications of the algebraic classification of tensors on Lorentzian manifolds of arbitrary dimension are discussed. We clarify some aspects of the relationship between invariants of tensors and their algebraic class, discuss generalization of Newman-Penrose and Geroch-Held-Penrose formalisms to arbitrary dimension and study an application of the algebraic classification to the case of quadratic gravity.
