This article provides an overview of the existing Bulgarian and foreign studies on the Baroque in Bulgarian literature. It notes the fact that the investigation of the problem was initiated by the Czech literary scholar V. Bechynova, whose ideas were later shared and further explored by the Bulgarian Slavists: E. Georgiev, P. Dinekov, K. Stanchev, L. Boeva, Y. Michakov, among others. Their studies identified the literatr communities and individual authors who were influenced by the Baroque style and determined the sources of Baroque influences. They also contributed to the systematization and periodization of the Bulgarian literary works containing traces of the Baroque mindset and stylistic code. The foreign scholars ((V. Bechynova, A. Angyal. A. Borowiec) confirmed the presence of the Baroque paradigm in Bulgarian literature and focused mainly on the literary production of the Bulgarian Catholics in the 17th century and the complex synthesis of the Baroque and Classicist traits in the early literature of the National Revival in the second half of the 19th century.
An analytical solution for nonlinear vibration of an initially stressed beam with elastic end restraints resting on two-parameter foundation is obtained. The mode functions for linear vibration of a beam with elastic end restraints resting on a linear elastic foundation are obtained first and used to solve the nonlinear vibration equation recalling elliptic integrals. The results obtained from the present solution are compared against those obtained from finite element method and found in close agreement. The effects of elastic support stiffnesses at the beam ends, foundation stiffness, initial axial load and vibration amplitude on the natural frequency are studied. and Obsahuje seznam literatury
