TL;DR: In this article, the authors give a characterization of real hyper-surface of type B, that is, a tube over a totally geodesic QP n in complex two-plane Grassmannians G2(C m+2 ), where m = 2n, with the Reeb vec- tor belonging to the distribution D, where D denotes a subdistribution in the tangent space such that TxM = D'D? for any point x 2 M and D? = Span{»1,»2,»3 }.

TL;DR: In this paper, the authors classify real hypersurfaces with Reeb invariant shape operator in complex hyperbolic two-plane Grassmannians and show that a tube over a totally geodesic manifold becomes a horosphere when the center at infinity is singular and of type JN \in {\mathfrak J}N$ for a unit normal vector field.

TL;DR: In this article, a new notion of D ⊥ -parallel shape operator for real hypersurfaces in complex two-plane Grassmannians G2(C m+2 ) was proposed and a non-existence theorem for a Hopf hypersurface in G2 (C m + 2 )w ithD ⊤ -paralell shape operator was given.

TL;DR: It was found that the PEP, a serine protease, plays an important role in degradation of the proline-containing neuropeptides such as oxytocin, vasopressin, substance P, neurotensin and angiotensin, which were suggested to participate in learning and memory processes.

TL;DR: In this article, a generalized Tanaka-Webster D-parallel shape operator for real hypersurfaces in a complex two-plane Grassmannian was proposed and a non-existence theorem was proved.
