Spectral Riesz-Cesaro means: How the square root function helps us to see around the world
Autor: S. A. Fulling, E. V. Gorbar, C. T. Romero
Publikováno v: Electronic Journal of Differential Equations, Vol Conference, Iss 04, Pp 87-101 (2000)
The heat-kernel expansion for a nonanalytic function of a differential operator, and the integrated (Cesà ro-smoothed) spectral densities associated with the corresponding nonanalytic function of the spectral parameter, exhibit a certain nonlocal be

Some properties of Riesz means and spectral expansions
Autor: S. A. Fulling, R. A. Gustafson
Publikováno v: Electronic Journal of Differential Equations, Vol 1999, Iss 06, Pp 1-39 (1999)
It is well known that short-time expansions of heat kernels correlate to formal high-frequency expansions of spectral densities. It is also well known that the latter expansions are generally not literally true beyond the first term. However, the ter

Distributional asymptotic expansions of spectral functions and of the associated Green kernels
Autor: R. Estrada, S. A. Fulling
Publikováno v: Electronic Journal of Differential Equations, Vol 1999, Iss 07, Pp 1-37 (1999)
Asymptotic expansions of Green functions and spectral densities associated with partial differential operators are widely applied in quantum field theory and elsewhere. The mathematical properties of these expansions can be clarified and more precise
