Pseudo-Diagonals and Uniqueness Theorems
We examine a certain type of abelian C*-subalgebras that allow one to give a
unified treatment of two uniqueness theorems: for graph C*-algebras and for
certain reduced crossed products
Higher Multiplicity in the One-Dimensional Allen-Cahn Action Functional
We prove the ¡-convergence of the Allen-Cahn action functional in
the sharp-interface limit. In previous work, good lower bounds were
developed under the assumption of single-multiplicity, but the bounds
deteriorated in the case of higher-multiplicity interfaces. We develop
improved bounds by working directly with the limiting energy measures
