Well-posedness for hyperbolic equations whose coefficients lose regularity at one point

Martino Prizzi, Daniele Del Santo

We prove some $C^{\infty}$ and Gevrey well-posedness results for hyperbolic equations whose coefficients lose regularity at one point.

On backward uniqueness for parabolic equations when Osgood continuity of the coefficients fails at one point

Daniele Del Santo, martino Prizzi

We prove uniqueness for backward parabolic equations whose coefficients are Osgood continuous in time for $t > 0$ but not at $t = 0$ .
