On asymptotic expansions of twisted products
(1989-12)
The series development of the quantum-mechanical twisted product is
studied. The series is shown to make sense as a moment asymptotic
expansion of the integral formula for the twisted product, either
pointwise or in the ...
On summability of distributions and spectral geometry
(1998-01)
Modulo the moment asymptotic expansion, the Cesàro and parametric behaviours of distributions at infinity are equivalent. On the strength of this result, we construct the asymptotic analysis for spectral densities arising ...
