comment “Lagrangian” subalgebra of cohomology, with respect to Poincare duality?
@ChrisMcDaniel: I was thinking of a compact manifold with the structure of a finite CW complex, and of X as being a subcomplex of that. But for the topological facts I stated you just need X and Y to have regular neighborhoods in M.

comment Algorithm to test for discrete or quasi-Fuchsian subgroups of PSL(2,C)
Real computation is what I had in mind. Certainly I would want to allow computing words in the generators of $\rho(\Gamma)$ and comparisons between traces or matrix entries as "basic operations". Thanks for your answers, which convince me there is no hope for an algorithm in general. As in the punctured torus case, when actually implementing such a test I will need to settle for heuristics that leave a thin set in the character variety "undecided".

I edited the last sentence to clarify that I am interested in the closed surface case.
