The Hadamard parametrix on half-Minkowski with Robin boundary conditions: Fundamental solutions and Hadamard states

B. Costeri, C. Dappiaggi, B. A. Juárez-Aubry +1

We address the problem of constructing fundamental solutions and Hadamard states for a Klein-Gordon field in half-Minkowski spacetime with Robin boundary conditions in $d\ge 2$ s…
