Abstract

There exist non-degenerate 3-form dωId\omega_I, ωI(X,Y)=g(IX,Y)\omega_I(X,Y)=g(IX,Y), for each leftinvariant almost Hermitian structure (g,I)(g,I), where gg is Killing-Cartan metric on the M=S3×S3=SU(2)×SU(2)M=S^3\times S^3=SU(2)\times SU(2). Known \cite{H1}, that arbitrary non-degenerate 3-form on the 6-dimensional manifold, with some additional properties defines the almost complex structure. Condition for II to define almost complex structure JIJ_I by dωId\omega_I is obtained. Properties of JIJ_I are researched.
