Differentiable structures on a generalized product of spheres
The author uses Munkres' obstruction theory [\textit{J. Munkres}, Ann. Math., II. Ser. 72, 521-554 (1960; Zbl 0108.181)] to classify all differentiable structures on a product of spheres \(S^{k_ 1}\times...\times S^{k_ r}\), where \(2\leq k_ 1<k_ 2\leq...\leq k_ r\), under the relation of orientation preserving diffeomorphism.
