Factorization of second-order strictly hyperbolic operators with logarithmic slow scale coefficients and generalized microlocal approximations
Martina Glogowatz
We give a factorization procedure for a strictly hyperbolic partial differential operator of second order with logarithmic slow scale coefficients. From this we can microlocally di…

Factorization of Second-order strictly hyperbolic operators with non-smooth coefficients and microlocal diagonalization
Martina Glogowatz
We study strictly hyperbolic partial differential operators of second order with non-smooth coefficients. After modelling them as semiclassical Colombeau equations of log-type we p…
