Abstract:

This paper proposes a new optimization framework to minimize geographical basis risk in weather index insurance by integrating extreme weather penalties and spatial regularization into strike temperature design. The model balances three objectives: (i) reducing payoff mismatches between local and reference stations, (ii) penalizing strike temperature that fail to account for heatwaves and cold spells, and (iii) ensuring smooth strike variations across geographically correlated stations.

Thesis Title: A Characterization of the alternating group A_n, for n≥8 by its fusion system over a sylow 2-subgroup

Abstract: This thesis aims to characterize the alternating group An, for n ≥ 8, by its fusion system over a Sylow 2-subgroup. The results here will contribute to Aschbacher’s programme which is aimed at providing a simplified proof of the theorem of classification of finite simple groups.

Abstract:

The University of Jena, Germany, offers English-taught MSc programmes in mathematics and business mathematics. We explain what it is like to study mathematics in Jena and what opportunities this opens up in academia and industry. We also explain the requirements and how to make an application successful.
