Local well-posedness and global analyticity for solutions of a generalized 0-equation

In this work we study the Cauchy problem in Gevrey spaces for a generalized class of equations that contains the case b = 0 of the b-equation. For the generalized equation, we prove that it is locally well-posed for initial data in Gevrey spaces. Moreover, as we move to global well-posedness, we show that for a particular choice of the parameter in the equation the local solution is global analytic in both time and spatial variables.
