On the Local solvability of a class of degenerate second order operators with complex coefficients
Serena Federico, Alberto Parmeggiani
We study the local solvability of a class of operators with multiple characteristics. The class considered here complements and extends the one studied in [9], in that in this pape…

Sufficient conditions for local solvability of some degenerate PDO with complex subprincipal symbol
Serena Federico
We will show a local solvability result for a class of degenerate second order linear partial differential operators with a complex subprincipal symbol. Due to the form of the oper…
