On the index of a non-Fredholm model operator
Let $\{A (t)\} _ {t\in\mathbb {R}} $ be a path of self-adjoint Fredholm operators in a Hilbert
space $\mathcal {H} $, joining endpoints $ A_\pm $ as $ t\to\pm\infty $. Computing the index …

Some applications of almost analytic extensions to operator bounds in trace ideals
Using the Davies-Helffer-Sj\" ostrand functional calculus based on almost analytic
extensions, we address the following problem: Given self-adjoint operators $ S_j $, $ j= 1 …
