Shi, and its generalization to (L, M)-fuzzy neighborhood systems, we introduce the notion of (L, M)-fuzzy topological group, and obtain various properties, including some results on quotient groups of (L, M)-fuzzy topological groups. We show that the category of (L, M)-fuzzy topological groups is topological over the category of groups with respect to the forgetful functor.<\/jats:p>","DOI":"10.3233\/ifs-130835","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T18:23:26Z","timestamp":1575311006000},"page":"1517-1526","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["(L, M)-fuzzy topological groups"],"prefix":"10.1177","volume":"26","author":[{"given":"Hu","family":"Zhao","sequence":"first","affiliation":[{"name":"College of Mathematics and Information Science, Shaanxi Normal University, Xi'an, P.R.
