# Local Zeta Regularization And The Scalar Casimir Effect: A General Approach Based On Integral Kernels

@inproceedings{Fermi2017LocalZR, title={Local Zeta Regularization And The Scalar Casimir Effect: A General Approach Based On Integral Kernels}, author={Davide Fermi and L. Pizzocchero}, year={2017} }

This is the first one of a series of papers about zeta regularization of the divergences appearing in the vacuum expectation value (VEV) of several local and global observables in quantum field theory. More precisely we consider a quantized, neutral scalar field on a domain in any spatial dimension, with arbitrary boundary conditions and, possibly, in presence of an external classical potential. We analyze, in particular, the VEV of the stress-energy tensor, the corresponding boundary forces… Expand
