Oh, I deleted it because I came up with a solution op[x,t][Exp[x t]]/Exp[x t], where I've actually gotten my polynomial, though with the variables that switched places. But your solution is much more generic, thanks again! Dec 3 comment How to define a differential operator? Thanks! Shame that it's a bit more complicated than I thought to get the roots of a polynomial, but that will work. Dec 3 accepted How to define a differential operator? Dec 3 comment How to define a differential operator? I am new to Mathematica, so my only guess was to create 2 distinct functions, one behaving like differential operator, other like a polynomial. I was wondering if there was a way to write it in 1 statement. Dec 3 asked How to define a differential operator?
