A topological group H is called ω -narrow if for everyneighbourhood V of it’s identity element there exists a countableset A such that V A = H = AV. A semigroup G is called a generalized group if for any x ∈ G there exists a unique element e(x) ∈ Gsuch that xe(x) = e(x)x = x and for every x ∈ G there existsx − 1 ∈ G such that x − 1x = xx − 1 = e(x). Also let G be a topological space and the operation and inversion mapping are continuous,then G is called a topological generalized group. If {e(x) | x ∈ G} iscountable and for any a ∈ G, {x ∈ G|e(x) = e(a)} is an ω-narrowtopological group, then G is called an ω-narrow topological generalized group. In this paper, ω-narrow and resolvable topologicalgeneralized groups are introduced and studied}, keywords = {ω-narrow topological generalized group,Resolvable topological generalizad group,Precompact topological generalized group,Invariance number}, url = {https://jas.shahroodut.ac.ir/article_1763.html}, eprint = {https://jas.shahroodut.ac.ir/article_1763_7eca9f8c7119e52f92adbafaae64e02c.pdf} }
