comment counting points on nilpotent Springer fiber
@JimHumphreys I'm not sure what the modular Springer correspondence has to do with anything. That is when the base field of the sheaf is finite, not the underlying variety (which is irrevelant for the category of constructible sheaves).

comment When is the induced representation factored through the initial one?
When $H$ is normal, then $\rho\circ \iota$ is a bunch of copies of $\pi$, so there the desired factoring is true.
