Abstract

Totally real submanifolds have been studied by many geometers in different ambient
manifolds. The purpose of this note is to study totally real submanifolds in Kaehlerian product manifolds.
We derive some integral formulas computing the Laplacian of the square of the second fundamental
form and using these formulas we prove pinching theorems. In fact, we have generalized
some results due to Yano and Kon [1,2] to the case when the ambient manifold is Kaehlerian product
manifold
