Heat Kernel Bounds for Elliptic Partial Differential Operators in Divergence Form with Robin-Type Boundary Conditions

Fritz Gesztesy, Marius Mitrea, Roger Nichols

One of the principal topics of this paper concerns the realization of self-adjoint operators $L_{Θ, \Om}$ in $L^2(\Om; d^n x)^m$, $m,n\in \mathbb{N}$, associated with divergence form e…
