Extremal length in higher dimensions and complex systolic inequalities [PDF]

open access: yes, 2020
Extremal length is a classical tool in 1-dimensional complex analysis for building conformal invariants. We propose a higher-dimensional generalization for complex manifolds and provide some ideas on how to estimate and calculate it.

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 ...

Real-analytic submanifolds of complex manifolds [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
This paper examines the extendibility of holomorphic functions on a real manifold which is embedded in a complex manifold. The principal result is that all real k-dimensional, real-analytic, compact manifolds embedded in an n-dimersional complex Stein manifold, where k >n, are extendible over a manifold of one higher real dimension.

On real submanifolds of Kähler manifolds foliated by complex submanifolds

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1994
Let \(X\) be a Kähler manifold, \(M\) a compact orientable real submanifold of \(X\), and suppose that \(M\) admits a foliation \(\mathfrak F\) whose leaves are complex submanifolds of \(X\) with complex dimension \(p\). The authors prove that if the \(p\)-th power of the Kähler form of \(X\) is exact when restricted to \(M\), then \(\mathfrak F\) has ...

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.

Kähler submanifolds of real and complex Riemannian manifolds

open access: yesMatemática Contemporânea, 1993
The purpose of this article is to present some inequalities involving the type component \(\alpha^{(1,1)}\) of the second fundamental form \(\alpha\) of a Kähler submanifold and give geometric interpretations to the cases where the equalities hold. Moreover, since the parallelism of \(\alpha^{(1,1)}\) is equivalent, in the case of surfaces, to the ...
