Features of the geometry of the five-dimensional pseudo-Euclidean space of index two [PDF]

E3S Web of Conferences
The article is devoted to the study of the geometry of subspaces of a five-dimensional pseudo-Euclidean space. This space is attractive because all kinds of semi-Euclidean, semi-pseudo-Euclidean, hyperbolic three-dimensional spaces with projective ...

Curvature-adapted submanifolds of symmetric spaces [PDF]

, 2012
We study curvature-adapted submanifolds of general symmetric spaces. We generalize Cartan's theorem for isoparametric hypersurfaces of spheres and Wang's classification of isoparametric Hopf hypersurfaces in complex projective spaces to any compact ...

The $C^*$-algebras of quantum lens and weighted projective spaces [PDF]

, 2016
It is shown that the algebra of continuous functions on the quantum $2n+1$-dimensional lens space $C(L^{2n+1}_q(N; m_0,\ldots, m_n))$ is a graph $C^*$-algebra, for arbitrary positive weights $ m_0,\ldots, m_n$.

On Free Quotients of Complete Intersection Calabi-Yau Manifolds [PDF]

, 2010
In order to find novel examples of non-simply connected Calabi-Yau threefolds, free quotients of complete intersections in products of projective spaces are classified by means of a computer search.

Cofinitely and co-countably projective spaces

Applied General Topology, 2002
We show that X is cofinitely projective if and only if it is a finite union of Alexandroff compactatifications of discrete spaces. We also prove that X is co-countably projective if and only if X admits no disjoint infinite family of uncountable cozero ...

The dual of the space of bounded operators on a Banach space

Concrete Operators, 2021
Given Banach spaces X and Y, we ask about the dual space of the 𝒧(X, Y). This paper surveys results on tensor products of Banach spaces with the main objective of describing the dual of spaces of bounded operators. In several cases and under a variety of

Pointed Trees Of Projective Spaces [PDF]

, 2008
We introduce a smooth projective variety T(d,n) which compactifies the space of configurations of it distinct points oil affine d-space modulo translation and homothety.

The Third, Fifth and Sixth Painlevé Equations on Weighted Projective Spaces [PDF]

, 2015
The third, fifth and sixth Painlev e equations are studied by means of the weighted projective spaces CP 3 (p;q;r;s) with suitable weights (p;q;r;s) determined by the Newton polyhedrons of the equations. Singular normal forms of the equations, symplectic

Stieltjes–Bethe equations in higher genus and branched coverings with even ramifications

Nuclear Physics B, 2018
We describe projective structures on a Riemann surface corresponding to monodromy groups which have trivial SL(2) monodromies around singularities and trivial PSL(2) monodromies along homologically non-trivial loops on a Riemann surface.

Metric measure limits of spheres and complex projective spaces [PDF]

, 2014
We study the limits of sequences of spheres and complex projective spaces with unbounded dimensions. A sequence of spheres (resp. complex projective spaces) either is a Levy family, infinitely dissipates, or converges to (resp.
