Mellin analysis of partial differential equations in papers of B. Ziemian
Existence and regularity theorems for Fuchsian type differential operators and the theory of second microlocalization are presented.
Existence and regularity theorems for Fuchsian type differential operators and the theory of second microlocalization are presented.
We study certain Fourier integral operators arising in the inversion of data from reflection seismology.
We obtain some microlocal estimates of the resonant states associated to a resonance of an -differential operator. More precisely, we show that the normalized resonant states are
