Title: Understanding Complex Social Systems using Minimal Mathematical Models Abstract: Minimal mathematical models are used to understand complex phenomena in the physical, biological, and social sciences. This modeling philosophy never claims, nor even attempts, to fully capture the mechanisms underlying the phenomena, and instead offers insights and predictions not otherwise possible. Here, we explore minimal […]
The Chow ring of heavy/light Hassett spaces via tropical geometry (Dagan Karp, HMC)
The Chow ring of heavy/light Hassett spaces via tropical geometry (Dagan Karp, HMC)
Hassett spaces in genus 0 are moduli spaces of weighted pointed stable rational curves; they are important in the minimal model program and enumerative geometry. We compute the Chow ring of heavy/light Hassett spaces. The computation involves intersection theory on the toric variety corresponding to a graphic matroid, and rests upon the work of Cavalieri-Hampe-Markwig-Ranganathan. […]
Projections on Banach spaces and a lifting property of operators (Prof. Botelho)
Projections on Banach spaces and a lifting property of operators (Prof. Botelho)
Title: Projections on Banach spaces and a lifting property of operators Prof. Maria Fernanda Botelho Department of Mathematical Sciences The University Of Memphis Abstract: In this talk I will present properties of contractive projections and explain their role in the existence of norm preserving lifts of operators. A pair of Banach spaces (X, J), with […]
