Para-Sasakian $\varphi$-symmetric spaces

Abstract

We study the Boothby-Wang fibration of para-Sasakian manifolds and introduce the class of para-Sasakian $\varphi$-symmetric spaces, canonically fibering over para-Hermitian symmetric spaces. Using this fibration we give a method to explicitly construct semisimple para-Sasakian $\varphi$-symmetric spaces. We provide moreover an example of non-semisimple para-Sasakian $\varphi$-symmetric space.
