Some classes of topological spaces and the space of G-permutation degree
Abstract In this paper, we study the behavior of some classes of topological spaces under the influence of the functor of G -permutation degree 𝖲𝖯Gn {\operatorname{\sf SP}^{n}_{G}} . We prove: (a) if a space X is an r -space, then so is 𝖲𝖯GnX {\operatorname{\sf SP}_{G}^{n}X} , (b) if X is a cosmic space, then so is 𝖲𝖯GnX {\operatorname{\sf SP}_{G}^{n}X} , (c) if a space X is a C(κ) {C(\kappa)} -cosmic, then so is 𝖲𝖯GnX {\operatorname{\sf SP}_{G}^{n}X} , (d) if a space X is an α-space, then so is 𝖲𝖯GnX {\operatorname{\sf SP}_{G}^{n}X} .
期刊介绍:
The Georgian Mathematical Journal was founded by the Georgian National Academy of Sciences and A. Razmadze Mathematical Institute, and is jointly produced with De Gruyter. The concern of this international journal is the publication of research articles of best scientific standard in pure and applied mathematics. Special emphasis is put on the presentation of results obtained by Georgian mathematicians.
