Ground states are a well-known class of Hadamard states in smooth spacetimes. In this paper, we show that the ground state of the Klein–Gordon field in a non-smooth ultrastatic spacetime is an adiabatic state. The order of the state depends linearl

We analyze a finite element/boundary element procedure to solve a non-convex contact problem for the double-well potential. After relaxing the associated functional, the degenerate minimization problem is reduced to a boundary/domain variational ineq

Realizations of differential operators subject to differential boundary conditions on manifolds with conical singularities are shown to have a bounded H ∞ -calculus in appropriate L p -Sobolev spaces provided suitable conditions of parameter-ellipt

We prove an index theorem of Atiyah–Singer type for Dirac operators on manifolds with a Lie structure at infinity ( Lie manifolds for short). With the help of a renormalized supertrace, defined on a suitable class of regularizing operators, the pro

We prove that parameter-elliptic extensions of cone differential operators have a bounded $$H_\infty $$ -calculus. Applications concern the Laplacian and the porous medium equation on manifolds with warped conical singularities.

Rouche’s Theorem is a standard topic in undergraduate complex analysis. It is usually covered near the end of the course with applications relating to pure mathematics only (e.g., using it to produce an alternate proof of the Fundamental Theorem of

We study the spectral flow of Landau-Robin hamiltonians in the exterior of a compact domain with smooth boundary. This provides a method to study the spectrum of the exterior Landau-Robin hamiltonian's dependence on the choice of Robin data, even exp

Given a Lie group $G$ of quantized canonical transformations acting on the space $L^2(M)$ over a closed manifold $M$, we define an algebra of so-called $G$-operators on $L^2(M)$. We show that to $G$-operators we can associate symbols in appropriate c
