• #### On the Invariants of the Cohomology of Complements of Coxeter Arrangements ﻿

[OWP-2018-21] (Mathematisches Forschungsinstitut Oberwolfach, 2018-10-22)
We refine Brieskorn's study of the cohomology of the complement of the reflection arrangement of a finite Coxeter group W. As a result we complete the verification of a conjecture by Felder and Veselov that gives an explicit ...
• #### An Optimal Bound for the Ratio Between Ordinary and Uniform Exponents of Diophantine Approximation ﻿

[OWP-2018-15] (Mathematisches Forschungsinstitut Oberwolfach, 2018-07-09)
We provide a lower bound for the ratio between the ordinary and uniform exponents of both simultaneous Diophantine approximation to n real numbers and Diophantine approximation for one linear form in n variables. This ...
