I have the following PDE
$\partial_t f(x,y,t)=cy (\partial_xf)+3x\partial_y(yf)+\frac{1}{2}c^2y^2(\partial_{xx}f) \\$
where $c \in \mathbb{R}$
I would like to know what type of PDE is, any information about it, and its possible solutions given an initial condition. In particular, I would like to know if every term on the right side forms a generator of a $C_0$ semigroup.
