We use the Weyl correspondence approach to investigate the spectral operators of the Laguerre and the Kautz systems. We show that the basic functions in the Lag
Toward Lions’ open question in Lions(1996) concerning the propagation of regularity for density patch, we prove that the boundary regularity of the 3-D density
In this paper, we study the Poisson stability(in particular, stationarity, periodicity, quasiperiodicity, Bohr almost periodicity, almost automorphy, recurrence
