@ARTICLE{Habibi, author = {Habibi, Parastoo and Razavi, Asadollah and }, title = {Generalized Symmetric Berwald Spaces}, volume = {9}, number = {1}, abstract ={In this paper we study generalized symmetric Berwald spaces. We show that if a Berwald space $(M,F)$ admits a parallel $s-$structure then it is locally symmetric. For a complete Berwald space which admits a parallel s-structure we show that if the flag curvature of $(M,F)$ is everywhere nonzero, then $F$ is Riemannian. }, URL = {http://ijmsi.ir/article-1-345-en.html}, eprint = {http://ijmsi.ir/article-1-345-en.pdf}, journal = {Iranian Journal of Mathematical Sciences and Informatics}, doi = {10.7508/ijmsi.2014.01.006}, year = {2014} }
