• #### Homological properties of piecewise hereditary algebras ﻿

[OWP-2009-11] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-05)
Let $\Lambda$ be a finite dimensional algebra over an algebraically closed field $k$. We will investigate homological properties of piecewise hereditary algebras $\Lambda$. In particular we give lower and upper bounds of ...
• #### A study on gradient blow up for viscosity solutions of fully nonlinear, uniformly elliptic equations ﻿

[OWP-2009-10] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-04)
We investigate sharp conditions for boundary and interior gradient estimates of continuous viscosity solutions to fully nonlinear, uniformly elliptic equations under Dirichlet boundary conditions. When these conditions are ...
• #### Stein's method for dependent random variables occuring in statistical mechanics ﻿

[OWP-2009-09] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-03)
We obtain rates of convergence in limit theorems of partial sums $S_n$ for certain sequences of dependent, identically distributed random variables, which arise naturally in statistical mechanics, in particular, in the ...
• #### Classification of idempotent states on the compact quantum groups Uq(2), SUq(2) and SOq(3) ﻿

[OWP-2009-08] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-02)
We give a simple characterisation of those idempotent states on compact quantum groups which arise as Haar states on quantum subgroups, show that all idempotent states on quantum groups $U_q(2)$, $SU_q(2)$, and \$SO_q(3) ...
