I am a theoretical physicist working in the area of quantum field theory, mostly QCD and gauge theories. I am also interested in mathematical problems related to the solution of PDEs.

comment Generality of a solution of a nonlinear PDE
Thanks a lot Robert. Would this imply that other kind of solutions could be expected as solitons and so on? How could be exploited all the set of solutions of a nonlinear PDE failing the superposition principle?
