Non-Newtonian compressible fluids with stochastic right hand side
Pavel Ludvík, Václav Mácha
Fluids with shear-rate-dependent viscosity form a special class of non-Newtonian fluids that play a crucial role in continuum dynamics. We consider a compressible barotropic flow o…
Parametric topological entropy of possibly discontinuous maps in compact Hausdorff spaces and hyperspaces
Pavel Ludvík, Jan Andres
We will consider various definitions of topological entropy for multivalued nonautonomous dynamical systems in compact Hausdorff spaces. Some of them can deal with arbitrary multiv…
Note on the metric entropy for multivalued maps
Jan Andres, Pavel Ludvík
The main aim of this note is to point out by means of counter-examples that some arguments of the proofs of two theorems about a "half variational principle" for multivalued maps,…
Distances to spaces of first resolvable class mappings
Pavel Ludvík
We study the mappings of the first resolvable class defined by G. Koumoullis as a valuable tool to address the point of continuity property in the non-metrizable setting. First, we…
