%0 Journal Article %T Semi-invariant submanifolds of (g, F)-manifolds %A Novac-Claudiu Chiriac %J Surveys in Mathematics and its Applications %D 2010 %I University Constantin Brancusi of Targu-Jiu %X We introduce (g,F)-manifolds and initiate a study of their semi-invariant submanifolds. These submanifolds are generalizations of CR-submanifolds of Kaehler manifolds. We obtain necessary and sufficient conditions for the integrability of distributions on a semi-invariant submanifold and study the geometry of foliations defined by these distributions. In particular, for a large class of (g,F)-manifolds we prove the existence of a natural foliation on their semi-invariant submanifolds. %K Semi-invariant submanifold %K (g %K F)-manifold %K Distribution %K Foliation %U http://www.utgjiu.ro/math/sma/v05/p15.pdf
