On the Gevrey well-posedness for weakly hyperbolic biwave type equations
Biagio Cassano, Giovanni Taglialatela
We study the Cauchy problem for biwave type equations with coefficients depending only on time. Assuming regularity of the principal symbol and suitable Levi condit…

On some hyperbolic equations of third order
Ferruccio Colombini, Todor Gramchev, Nicola Orrù +1
We give sufficient conditions for the well-posedness in of the Cauchy problem for third order equations with time dependent coefficients.

The Cauchy Problem for properly hyperbolic equations in one space variable
Sergio Spagnolo Giovanni Taglialatela
In this paper we consider the Cauchy problem for higher order weakly hyperbolic equations. We assume that the principal symbol depends only on one space variable and the characteri…
