Perverse-sheaf Singer–Hopf conjecture for aspherical projective manifolds

Let XX be an aspherical projective manifold and let P\mathcal{P} be a perverse sheaf on XX. Perverse-sheaf Singer–Hopf conjecture. The Euler characteristic of P\mathcal{P} is semipositive:

χ(X,P)0.\chi(X,\mathcal{P})\geq 0.

This is proposed as a projective generalization of the Singer–Hopf conjecture and is presented as open in the source.
