Omoloye Ajala, Samuel Differentiable structures on a generalized product of spheres. (English) Zbl 0627.57022 Int. J. Math. Math. Sci. 10, 217-226 (1987). The author uses Munkres’ obstruction theory [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.
