Projective toric designs, quantum state designs, and mutually unbiased bases [PDF]

open access: yesQuantum
Toric $t$-designs, or equivalently $t$-designs on the diagonal subgroup of the unitary group, are sets of points on the torus over which sums reproduce integrals of degree $t$ monomials over the full torus.

Centered planes in the projective connection space

open access: yesДифференциальная геометрия многообразий фигур, 2020
The space of centered planes is considered in the Cartan projec­ti­ve connection space . The space is important because it has con­nec­tion with the Grassmann manifold, which plays an important role in geometry and topology, since it is the basic space ...

A new two--parameter family of isomonodromic deformations over the five punctured sphere [PDF]

open access: yes, 2016
The object of this paper is to describe an explicit two--parameter family of logarithmic flat connections over the complex projective plane. These connections have dihedral monodromy and their polar locus is a prescribed quintic composed of a circle and ...

Rigid irregular connections on P^1 [PDF]

open access: yes, 2010
N.Katz's middle convolution algorithm provides a description of rigid connections on the projective line with regular singularities. We extend the algorithm by adding the Fourier transform to it.

Motivational Conflicts and the Psychological Structure of Perfectionism in Patients with Anxiety Disorders and Patients with Essential Hypertension

open access: yesBehavioral Sciences, 2020
Many studies have shown connections between perfectionism, motivation, and anxiety disorders (AD), as well as essential hypertension (EH). The objective of this study is to examine the connections between motivation and the structure of perfectionism in ...

Geodesics on a supermanifold and projective equivalence of super connections [PDF]

open access: yes, 2012
We investigate the concept of projective equivalence of connections in supergeometry. To this aim, we propose a definition for (super) geodesics on a supermanifold in which, as in the classical case, they are the projections of the integral curves of a ...

Benenti Tensors: A useful tool in Projective Differential Geometry

open access: yesComplex Manifolds, 2018
Two metrics are said to be projectively equivalent if they share the same geodesics (viewed as unparametrized curves). The degree of mobility of a metric g is the dimension of the space of the metrics projectively equivalent to g. For any pair of metrics

Delusion disorder: Neuropsychological aspects [PDF]

open access: yesPsihologija, 2004
Previous studies concerned with neuropsychological aspect of delusions, were mainly focused on specific forms of this disorder. Comparatively small number of investigations were concerned with cognitive deficiencies accompanying the delusions.

On real projective connections, V.I. Smirnov's approach, and black hole type solutions of the Liouville equation [PDF]

open access: yes, 2015
We consider real projective connections on Riemann surfaces and corresponding solutions of the Liouville equation. It is shown that these solutions have singularities of special type (of a black hole type) on a finite number of simple analytical contours.
