On two tensors associated to the structure Jacobi operator of a real hypersurface in complex projective space [PDF]

Periodica Mathematica Hungarica, 2022
A real hypersurface M in a complex projective space inherits an almost contact metric structure from the Kählerian structure of the ambient space. This almost contact metric structure allows us to define, for any nonzero real number k, the so-called k ...

On the bit complexity of finding points in connected components of a smooth real hypersurface

International Symposium on Symbolic and Algebraic Computation, 2020
We present a full analysis of the bit complexity of an efficient algorithm for the computation of at least one point in each connected component of a smooth real hypersurface.

Real hypersurfaces in the complex quadric with generalized Killing shape operator

Journal of Geometry and Physics, 2021
In this paper, we introduce a notion of generalized Killing shape operator (or called the quadratic Killing shape operator) and its geometric meaning on real hypersurfaces in the complex quadric.

Generalized Killing Ricci tensor for real hypersurfaces in complex two-plane Grassmannians

In this paper, first we introduce a new notion of generalized Killing Ricci tensor for a real hypersurface M in complex two-plane Grassmannians G 2 ( ℂ m + 2 ) .

ON LOCAL AUTOMORPHISMS OF REAL ANALYTIC HYPERSURFACES

Mathematics of the USSR-Izvestiya, 1982
In this paper the author studies biholomorphic transformations of carrying a nondegenerate real analytic surface into itself and leaving a particular point fixed. The first estimates of the dimensions of such groups of transformations were obtained by V. K. Belosapka (see MR 80h: 32039).

Distance-Genericity for Real Algebraic Hypersurfaces

Canadian Journal of Mathematics, 1984
One of the original applications of catastrophe theory envisaged by Thom was that of discussing the local structure of the focal set for a (generic) smooth submanifold M ⊆ Rn + 1. Thom conjectured that for a generic M there would be only finitely many local topological models, a result proved by Looijenga in [4].

Real Hypersurfaces, Orders of Contact, and Applications

The Annals of Mathematics, 1982
A fundamental problem in the modem theory of several complex variables concerns the boundary behavior of the Cauchy-Riemann equations. Suppose that D is an open domain in Cn, and that its boundary, M, is a smooth real submanifold of Cn. How does the geometry of M influence the function theory on D? One approach to this question is the a-Neumann problem,
