Classification of Levi-spherical Schubert varieties

Selecta Mathematica, 2021
A Schubert variety in the complete flag manifold $$GL_n/B$$ G L n / B is Levi-spherical if the action of a Borel subgroup in a Levi subgroup of a standard parabolic has an open dense orbit.

Levi-Civita connections for a class of spectral triples

Letters in Mathematical Physics, 2018
We give a new definition of Levi-Civita connection for a noncommutative pseudo-Riemannian metric on a noncommutative manifold given by a spectral triple.

Levi-Civita Ricci-flat metrics on compact complex manifolds

Journal of Geometric Analysis, 2018
In this paper, we study the geometry of compact complex manifolds with Levi-Civita Ricci-flat metrics and prove that compact complex surfaces admitting Levi-Civita Ricci-flat metrics are Kähler Calabi-Yau surfaces or Hopf surfaces.

Minimal Complex Surfaces with Levi–Civita Ricci-flat Metrics

, 2017
This is a continuation of our previous paper [14]. In [14], we introduced the first Aeppli–Chern class on compact complex manifolds, and proved that the (1, 1) curvature form of the Levi–Civita connection represents the first Aeppli–Chern class which is ...

Levi's Lemma, pseudolinear drawings of Kn , and empty triangles

Journal of Graph Theory, 2015
There are three main thrusts to this article: a new proof of Levi's Enlargement Lemma for pseudoline arrangements in the real projective plane; a new characterization of pseudolinear drawings of the complete graph; and proofs that pseudolinear and convex

Levy-Reid Hypothesis

Brain and Language, 1993
The inconsistencies in the research findings looking to test for the Levy-Reid hypothesis on the relationship between hand posture and laterality have been accounted for in various ways. Some authors (Cohen, 1991; Weber and Bradshaw, 1981) have suggested that existing methodologies for experimentally establishing laterality of language functioning are ...

Levy-Hollister Syndrome

Pediatrics, 1988
The Levy-Hollister syndrome is an autosomal dominant disorder characterized by lacrimal malformations, simple cup-shaped ears, hearing loss, hypodontia and enamel dysplasia, and upper limb malformations. Renal anomalies have been noted variably. Two families with this disorder have been described previously.
