Special half lightlike submanifolds of an indefinite cosymplectic manifold (Q1757913)

Summary: We study the geometry of half light-like submanifolds \(M\) of an indefinite cosymplectic manifold \(\bar{M}\). First, we construct two types of half light-like submanifolds according to the form of the structure vector field of \(\bar{M}\), called tangential and ascreen half light-like submanifolds. Next, we characterize the light-like geometries of these two types of half light-like submanifolds.
