SUMMARY:Andrzej BIS (University of Lodz\, Poland): Entropy\, pressure and v
 ariational principle of semi-group actions
DESCRIPTION:Andrzej BIS: The Krilov-Bogoliubov Theorem says that for contin
 uous map $f:X \\to X\,$ of a compact metric space $X\,$ there exists an $f
 -$invariant Borel probability measure. This result is essential in stating
  the variational principle for a single map.\nThere is no counterpart of t
 he Krilov-Bogoliubov Theorem for a finitely generated semi-group of contin
 uous maps. During the talk I will provide some estimation of topological e
 ntropy (in sense of Ghys\, Langevin and Walczak) of a finitely generated s
 emi-group action. Also\, I will present a recent joint result with M. Carv
 alho\, M. Mendes and P. Varandas on a general variational principle relate
 d to a pressure function.\n[su_spacer]\nZoom : https://univ-amu-fr.zoom.us
