Bianchi spaces and their 3-dimensional isometries as S-expansions of 2-dimensional isometries
Ricardo Caroca, Igor Kondrashuk, Nelson Merino +1
In this paper we show that some 3-dimensional isometry algebras, specifically those of type I, II, III and V (according Bianchi's classification), can be obtained as expansions of…
