The axiom of cosymplectic surfaces and $W_4$-manifolds
M. B. Banaru Smolensk State University
Abstract:
An almost Hermitian manifold satisfies the cosymplectic $t$-hypersurfaces axiom, if a cosymplectic hypersurface with type number $t$ passes through every its point. It is proved that if an arbitrary $W_4$-manifold satisfies the cosymplectic $t$-hypersurfaces axiom with $t\leq1$, then this manifold is Kählerian.
Key words:
almost contact metric structure, cosymplectic structure, type number, hypersurface, $W_4$-manifold.
