From geometry to dynamics. Integrable bilinear discretizations of quadratic vector fields
Tuesday, November 9, 2021, 16:00 GMT
Abstract: We discuss dynamics of birational maps which appear as bilinear discretizations of quadratic vector fields. The corresponding dynamical systems turn out to be integrable much more often than could be expected a priori. Recently, geometric constructions behind integrable discretizations of this kind have been discovered. We will discuss these constructions, along with various aspects of integrability of birational dynamical systems in general.
