SOME INVESTIGATIONS IN KAEHLERIAN TACHIBANA H-CONCIRCULAR RECURRENT AND SYMMETRIC SPACES OF SECOND ORDER

摘要

Tachibana (1967) and Mathai (1969) studied and defined the Bochner curvature tensor and Kaehlerian recurrent spaces respectively. Singh (1971-72) studied and defined Kaehlerian recurrent and Ricci-recurrent spaces of second order. In the present paper, we have studied and defined Kaehlerian Tachibana H-Concircular recurrent and symmetric spaces of second order also several theorems have been investigated and proved therein. The necessary and sufficient condition for a ~2T_n-space to be ~2P_n-space have been established.
