• #### Stratifying modular representations of finite groups ﻿

[OWP-2008-20] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-20)
We classify localising subcategories of the stable module category of a finite group that are closed under tensor product with simple (or, equivalently all) modules. One application is a proof of the telescope conjecture ...
• #### Upper tails for intersection local times of random walks in supercritical dimensions ﻿

[OWP-2008-02] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-06)
We determine the precise asymptotics of the logarithmic upper tail probability of the total intersection local time of $p$ independent random walks in $\mathbb{Z}^d$ under the assumption $p(d-2)>d$. Our approach allows a ...
• #### Urn Models & Operator Ordering Procedures ﻿

[OWP-2008-06] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-10)
Ordering of operators is purely combinatorial task involving a number of commutators shuffling components of operator expression to desired form. Here we show how it can be illustrated by simple urn models in which normal ...
• #### Weyl-Titchmarsh Functions of Vector-Valued Sturm-Liouville Operators on the Unit Interval ﻿

[OWP-2008-13] (Mathematisches Forschungsinstitut Oberwolfach, 2008)
The matrix-valued Weyl-Titchmarsh functions $M(\lambda)$ of vector-valued Sturm-Liouville operators on the unit interval with the Dirichlet boundary conditions are considered. The collection of the eigenvalues (i.e., poles ...
