Spectral Sequences in Combinatorial Geometry: Cheeses, Inscribed Sets, and Borsuk-Ulam Type Theorems
[OWP-2010-08] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-12)Algebraic topological methods are especially suited to determining the nonexistence of continuous mappings satisfying certain properties. In combinatorial problems it is sometimes possible to define a mapping from a space ... -
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 ... -
Tilting on non-commutative rational projective curves
[OWP-2009-14] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-08)In this article we introduce a new class of non-commutative projective curves and show that in certain cases the derived category of coherent sheaves on them has a tilting complex. In particular, we prove that the right ... -
Weighted Fourier inequalities for radial functions
[OWP-2009-26] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-19)Weighted $L^p(\mathbb{R}^n) \to L^q(\mathbb{R}^n)$ Fourier inequalities are studied. We prove Pitt-Boas type results on integrability with power weights of the Fourier transform of a radial function.
