We consider manifolds $M^{2n}$ which admit smooth maps into a connected sum of $S^1\times S^n$ with only finitely many critical points, for $n\in\{2,4,8\}$, and compute the minimal number of critical points.
Morse functions with four critical points on immersed 2-spheres
Manifolds which admit maps with finitely many critical points into spheres of small dimensions
