Factorization of second-order strictly hyperbolic operators with non-smooth coefficients and microlocal diagonalization
We study strictly hyperbolic partial differential operators of second-order with non-smooth coefficients. After modeling them as semiclassical Colombeau equations of log-type we provide a factorization procedure on some time-space-frequency domain. As a result the operator is written as a produc...
