Description:
When comparing the fate of Bohuslav Martinů to that of his pupil Jan Novák, interesting parallels can be found, not only in their work (with which this article does not deal), but also in their lives. Both composers met in 1947 in the U.S.A., and, for half a year, they worked together in New York. Novák’s 1950s compositions were strongly influenced by Martinů’s style. At the same time, both of them suffered the disgrace of the Czechoslovak cultural politics and its executors. Novák venerated Martinů as his model up to the end of his life, even if during the 1960s he reverted from the neo-classical style to the principles of New music, dodecaphony and serialism. As performers, Jan Novák and his wife Eliška played an important role in creating a positive picture of Martinů, and promoting his works in Czechoslovakia during the difficult time of the early 1950s. An outcome of his free attitudes, which put Novák in permanent opposition with the ruling regime, was, in the same way as with Martinů, a life-long emigration in free Western Europe. Today, we have to secure for his music a dignified position in our violated music history as well as on our concert stages.

3. Nonlinear vibration of 2D viscoelastic plate subjected to tangential follower force

Subject:
nonlinear vibration, multi-scales method, and differential quadrature method
Language:
English
Description:
In this paper, the problem of nonlinear viscoelastic rectangular thin plate subjected to tangential follower force is examined. The nonlinear strain-displacement relation is used to express non-linearity. After obtaining the equilibrium equation of the system in Laplace domain and performing the Laplace inverse transformation, the nonlinear differential equation of plate constituted by Kelvin-Voigt model and subjected to tangential follower force in time domain is obtained. Multi-scales method is firstly used to solve the governing equation, and the influence of the initial amplitude on the nonlinear frequency ratio is studied. Secondly, the differential quadrature method (DQM) is employed to confirm the obtained results. and Obsahuje seznam literatury

4. Properties of a hypothetical exotic complex structure on CP3

Brown, J. R

Type:
model:article and TEXT
Subject:
complex structure, projective space, Frölicher spectral sequence, and Hodge numbers
Language:
English
Description:
We consider almost-complex structures on ℂP 3 whose total Chern classes differ from that of the standard (integrable) almost-complex structure. E. Thomas established the existence of many such structures. We show that if there exists an ''exotic'' integrable almost-complex structures, then the resulting complex manifold would have specific Hodge numbers which do not vanish. We also give a necessary condition for the nondegeneration of the Frölicher spectral sequence at the second level.
