Well-posedness results for hyperbolic operators with coefficients rapidly oscillating in time

Ferruccio Colombini, Daniele Del Santo, Francesco Fanelli

In the present paper, we consider second order strictly hyperbolic linear operators of the form $Lu={\partial }_t^{2}u-\mathrm{div}(A(t,x)\nabla u)$, for $(t,x)\in[0,T]\tim…
