Real analytic manifolds in n with parabolic complex tangents along a submanifold of codimension one [PDF]

open access: yesAnnales de la Faculté des sciences de Toulouse : Mathématiques, 2009
We will classify n-dimensional real submanifolds in ℂ n which have a set of parabolic complex tangents of real dimension n-1. All such submanifolds are equivalent under formal biholomorphisms. We will show that the equivalence classes under convergent local biholomorphisms form a moduli space of infinite dimension.

The Hodge conjecture: The complications of understanding the shape of geometric spaces

open access: yesMètode Science Studies Journal: Annual Review, 2018
The Hodge conjecture is one of the seven millennium problems, and is framed within differential geometry and algebraic geometry. It was proposed by William Hodge in 1950 and is currently a stimulus for the development of several theories based on ...

D-Branes and Spin^c Structures [PDF]

open access: yes, 1998
It was recently pointed out by E. Witten that for a D-brane to consistently wrap a submanifold of some manifold, the normal bundle must admit a Spin^c structure.

Some examples of special Lagrangian tori

open access: yes, 1999
I point out some very elementary examples of special Lagrangian tori in certain Calabi-Yau manifolds that occur as hypersurfaces in complex projective space. All of these are constructed as real slices of smooth hypersurfaces defined over the reals. This

Gauge theory in dimension $7$

open access: yes, 2009
We first review the notion of a $G_2$-manifold, defined in terms of a principal $G_2$ ("gauge") bundle over a $7$-dimensional manifold, before discussing their relation to supergravity. In a second thread, we focus on associative submanifolds and present

Intersections of quadrics, moment-angle manifolds, and Hamiltonian-minimal Lagrangian embeddings

open access: yes, 2013
We study the topology of Hamiltonian-minimal Lagrangian submanifolds N in C^m constructed from intersections of real quadrics in a work of the first author.

"Universal" inequalities for the eigenvalues of the biharmonic operator [PDF]

open access: yes, 2009
In this paper, we establish universal inequalities for eigenvalues of the clamped plate problem on compact submanifolds of Euclidean spaces, of spheres and of real, complex and quaternionic projective spaces.

Geometry of warped product semi-slant submanifolds of Kenmotsu manifolds

open access: yes, 2017
In this paper, we study semi-slant submanifolds and their warped products in Kenmotsu manifolds. The existence of such warped products in Kenmotsu manifolds is shown by an example and a characterization.

Cycles, submanifolds, and structures on normal bundles

open access: yes, 2001
We give explicit examples of degree 3 cohomology classes not Poincare dual to submanifolds, and discuss the realisability of homology classes by submanifolds with Spin-C normal bundles.Comment: Several changes including an improvement of Theorem 1, our ...

Ruled CR-submanifolds of locally conformal K\"{a}hler manifolds

open access: yes, 2012
The purpose of this paper is to study the canonical totally real foliations of CR-submanifolds in a locally conformal K\"{a}hler manifold.Comment: 10 pages, Journal of Geometry and Physics (to ...
