A Toeplitz corona theorem for the pentablock and applications

We state and prove a Toeplitz corona theorem for the pentablock $\mathbb{P}$, a domain in $\mathbb{C}^3$ given by \[ \mathbb{P}=\{(a_{21}, \text{tr}(A), \det(A)) \in \mathbb C^3 : A=[a_{ij}] \in M_2(\mathbb C), \|A\|<1\}. \] By two different applications of this theorem, we obtain a few new characterizations in the Toeplitz corona theorems for the ...

Corona theorems for subalgebras of H∞∩Qtp

Journal of Mathematical Analysis and Applications
AbstractThe main goal of this work is to give a unified proof of several corona theorems for a collection of algebras of pointwise multipliers of spaces of holomorphic functions on the unit disk D. These spaces include Besov spaces, invariant Dirichlet type spaces, weighted Sobolev spaces and Carleson measure spaces for Besov spaces.

A Unifying Impossibility Theorem [PDF]

This paper considers social choice correspondences assigning a choice set to each non-empty subset of social alternatives. We impose three requirements on these correspondences: unanimity, independence of preferences over infeasible alternatives and ...

Dilworth's Theorem Revisited, an Algorithmic Proof [PDF]

Dilworth's theorem establishes a link between a minimal path cover and a maximal antichain in a digraph.A new proof for Dilworth's theorem is given. Moreover an algorithm to find both the path cover and the antichain, as considered in the theorem, is ...
