• #### Locally conformally Kähler manifolds admitting a holomorphic conformal flow ﻿

[OWP-2010-13] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-15)
A manifold $M$ is locally conformally Kähler (LCK) if it admits a Kähler covering $\tilde{M}$ with monodromy acting by holomorphic homotheties. Let $M$ be an LCK manifold admitting a holomorphic conformal flow of ...
• #### On Selfinjective Artin Algebras Having Generalized Standard Quasitubes ﻿

[OWP-2010-18] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-18)
We give a complete description of the Morita equivalence classes of all connected selfinjective artin algebras for which the Auslander-Reiten quiver admits a family of quasitubes having common composition factors, closed ...
• #### Plethysms, replicated Schur functions and series, with applications to vertex operators ﻿

[OWP-2010-12] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-14)
Specializations of Schur functions are exploited to define and evaluate the Schur functions $s_\lambda [\alpha X]$ and plethysms $s_\lambda [\alpha s_\nu(X))]$ for any $\alpha$-integer, real or complex. Plethysms are then ...
• #### Semi-Invertible Extensions of C*-Algebras ﻿

[OWP-2010-17] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-17)
We prolonge the list of $C^*$-algebras for which all extensions by any stable separable $C^*$-algebra are semi-invertible. In particular, we handle certain amalgamations, both of $C^*$-algebras and of groups. Concerning ...
• #### Shape Theory and Extensions of C*-Algebras ﻿

[OWP-2010-16] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-16)
Let A, A' be separable $C^*$-algebras, $B$ a stable $\sigma$-unital $C^*$-algebra. Our main result is the construction of the pairing $[[A', A]] \times Ext^{-1/2}(A,B) \to Ext^{-1/2}(A',B)$, where $[[A', A]]$ denotes the ...
• #### Stochastic mean payoff game: smoothed analysis and approximation schemes ﻿

[OWP-2010-22] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-20)
We consider two-person zero-sum stochastic mean payoff games with perfect information modeled by a digraph with black, white, and random vertices. These BWR-games games are polynomially equivalent with the classical Gillette ...
• #### Unconditional Convergence of Spectral Decompositions of 1D Dirac Operators with Regular Boundary Conditions ﻿
