On The Manifolds Of Positive Curvature, Jasurbek Aslonov
On The Manifolds Of Positive Curvature, Jasurbek Aslonov
Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
In this paper invariant metrics on Lie group $G=S^3\times R$ are studied and it is found lower and upper bounds for the sectional curvature's of the manifold $G=S^3\times R$.
Some Cardinal And Topological Properties Of The N-Permutation Degree Of A Topological Spaces And Locally Τ-Density Of Hyperspaces, Farkhod Mukhamadiev
Some Cardinal And Topological Properties Of The N-Permutation Degree Of A Topological Spaces And Locally Τ-Density Of Hyperspaces, Farkhod Mukhamadiev
Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
In the paper we investigate some cardinal and topological properties of the n-permutation degree of a topological spaces and locally τ-density of hyperspaces. It is proved that the functors expn and SPn preserves locally τ-density of any infinite T1-spaces.
