Title: A Note on the CR Cohomology of Levi-Flat Minimal Orbits in Complex Flag Manifolds Authors: Altomani, Andrea Abstract: We prove a relation between the $\bar{\partial}_{M}$ cohomology of a minimal orbit of M of a real form of $\mathbf{G}_{0}$ of a complex semisimple Lie group $\mathbf{G}$ in a flag manifold $\mathbf{G}/\mathbf{Q}$ and the Dolbeault cohomology of the Matsuki dual open orbit X of the complexification $\mathbf{K}$ of a maximal compact subgroup $\mathbf{K}_{0}$ of $\mathbf{G}_{0}$, under the assumption that M is Levi-flat.

Title: Lifting Finite Groups of Outer Automorphisms of Free Groups, Surface Groups and their Abelianizations Authors: Zimmermann, Bruno P. Abstract: In the present note, in part written as a survey, we discuss the possibility of lifting finite subgroups, and in particular finite cyclic subgroups, with respect to the canonical projections between automorphism and outer automorphism groups of free groups, surface groups and their abelianizations.

Title: Some Nonexistence Results for Systems of Nonlinear Partial Differential Inequalities Authors: Galakhov, Evgeny Abstract: We obtain nonexistence results for systems of stationary and evolutional partial differential inequalities that involve p-Laplacian and similar nonlinear operators as well as gradient nonlinearities. Our proofs are based on the nonlinear capacity method. Type: Articolo

Title: On Self-Injectivity and p-Injectivity Authors: Yue Chi Ming, Roger Abstract: A generalization of injectivity is studied and several properties are developed. Von Neumann regular rings are characterized. Sufficient conditions are given for a ring to admit a strongly regular classical left quotient ring. A nice characterization of strongly regular rings is given. Special direct summands of left self-injective regular and left continuous regular rings are considered. Type: Articolo
