Conformal changes of generalized paracontact pseudometric structures

Abstract

We characterize generalized almost paracontact pseudometric structures after a conformal change andinvestigate invariant components of these structures under conformal changes. Then we characterize the conformalchanges of normal generalized paracontact pseudometric structures, generalized almost para-co-Kähler structures, andgeneralized para-co-Kähler structures. We also give examples of a generalized almost para-co-Kähler structure and anormal generalized paracontact pseudometric structure that remains invariant under a nonhomothety conformal change.
