Resumen de Conformal and related changes of metric on the product of two almost contact metric manifolds

José Antonio Oubiña Galiñanes , D. E. Blair

• This paper studies conformal and related changes of the product metric on the product of two almost contact metric manifolds. It is shown that if one factor is Sasakian, the other is not, but that locally the second factor is of the type studied by Kenmotsu. The results are more general and given in terms of trans-Sasakian, a-Sasakian and ß-Kenmotsu structures.
