Abstract

Using generalized Tanaka-Webster connection, we considered a real hypersurface MM in a complex two-plane Grassmannian G2(Cm+2)G_2({\mathbb C}^{m+2}) when the GTW Reeb Lie derivative of the structure Jacobi operator coincides with the Reeb Lie derivative. Next using the method of simultaneous diagonalization, we prove a complete classification for a real hypersurface in G2(Cm+2)G_2({\mathbb C}^{m+2}) satisfying such a condition. In this case, we have proved that MM is an open part of a tube around a totally geodesic G2(Cm+1)G_2({\mathbb C}^{m+1}) in G2(Cm+2)G_2({\mathbb C}^{m+2}).
