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 condi…

On the strong unique continuation property for the Dirac operator
Biagio Cassano
In [DO99,KY99], the strong unique continuation property from the origin is established for -solutions to the massless Dirac differential inequality $|{D}_n u | \leq \fra…
