used to be , sadly ! in my early seventies and haven't used any high level maths for half a century and lost it . But not a mathematician as such .... a chemist ...but we studied Schroedingers wave equation which did have practical application and quite a bit (too much actualy) physics(largely mechanics) ....things that were never useful past study .
So very likely your maths would be considerably better than mine now . I might also offer as excuse reading all these brain numbing posts on HC !
