In this paper, we study the LS-category and topological complexity of these manifolds. We determine the exact value of the LS-category and in many cases, the topological complexity of these manifolds. We also obtain tight bounds on the topological complexity of these manifolds. It is known that Milnor manifolds admit $\\mathbb{Z}_2$ and circle actions. We compute bounds on the equivariant LS-category and equivariant topological complexity of these manifolds. Finally, we describe the mod-$2$ cohomology rings of some generalized projective product spaces corresponding to Milnor manifolds and use this information to compute the bound on LS-category and topological complexity of these spaces.", "revisions": [ { "version": "v2", "updated": "2023-08-23T21:25:36.000Z" } ], "analyses": { "subjects": [ "55M30", "55P15", "57N65" ], "keywords": [ "topological complexity", "corresponding generalized projective product spaces", "ls-category", "projective product spaces corresponding", "milnor manifolds admit" ], "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable" } } }
