Does there exist any analogue of the method for solving quintic equtions for polynomials of degree $n > 5$? i. e. a method of expressing roots in terms of some reasonable special functions of coefficients in a computable way?
I know that 'reasonable' is extremely vague here. I mean functions which has been investigated in some other context or ones which fit into 'nice' families governed by parameters from $\mathbb{N}$, say, as solutions to a family of ODEs.
I suppose that the answer should be 'no', since otherwise no one would care about solutions to the polynomials of degree 5 with elliptic functions.
