Colloquium

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…

You are also welcome to join us on Zoom at: https://us02web.zoom.us/j/83337601824 Time: 14:00 Abstract: The dimension of the space of multilinear products of higher commutators is equal to the number of derangements, $[e^{-1}n!]$. Our search for a combinatorial explanation for this…

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…

The zoom link for our meetings is: https://us02web.zoom.us/j/83337601824 Time: 14:00 Abstract:  Hilbert’s Nullstellensatz on zero sets of polynomials is one of the most fundamental correspondences between algebra and geometry. In recent years, there has been an emerging interest in polynomial equations and…
