Anisotropic Lavine's formula and symmetrised time delay in scattering theory
Rafael Tiedra de Aldecoa
We consider, in quantum scattering theory, symmetrised time delay defined in terms of sojourn times in arbitrary spatial regions symmetric with respect to the origin. For potential…

Spectral analysis for convolution operators on locally compact groups
Marius Mantoiu, Rafael Tiedra de Aldecoa
We consider operators of convolution with measures on locally compact groups. We characterize the spectrum of by constructing auxiliary operators whose kernel conta…
