Ramsey’s theorem, , holds for the countable infinity and has many useful applications, but, as Sierpinski discovered, fails for the real line: . Strong anti-Ramsey relations are known on many uncountable cardinals and have application in general topology.   In the talk we…

The zoom link for our meetings is:https://us02web.zoom.us/j/83337601824 Abstract: Zeta functions are ubiquitous in mathematics. In algebra and geometry, they often have an enumerative interpretation, prominent examples being the Dedekind zeta function of a number field and the (Weil) zeta function of…

Will be on Zoom https://us02web.zoom.us/j/83337601824 Time: 14:00 Abstract: Pointwise ergodic theorems provide a bridge between the global behaviour of the dynamical system and the local combinatorial statistics of the system at a point. Such theorems have been proven in different contexts, but…
