Orthogonal apartments in Hilbert Grassmannians

Mark Pankov

Let $H$ be an infinite-dimensional complex Hilbert space and let $L (H)$ be the logic formed by all closed subspaces of $H$ . For every natural $k$ we denote by ${\mathcal…

Minimal surfaces in the soliton surface approach

A Doliwa, A M Grundland

The main objective of this paper is to derive the Enneper-Weierstrass representation of minimal surfaces in $E^{3}$ using the soliton surface approach. We exploit the Bryant…

Elementary Superconductivity in Nonlinear Electrodynamics Coupled to Gravity

Irina Dymnikova

Source-free equations of nonlinear electrodynamics minimally coupled to gravity admit regular axially symmetric asymptotically Kerr-Newman solutions which describe charged rotating…

Regular rotating electrically charged black holes and solitons in nonlinear electrodynamics minimally coupled to gravity

Irina Dymnikova, Evgeny Galaktionov

In nonlinear electrodynamics coupled to gravity, regular spherically symmetric electrically charged solutions satisfy the weak energy condition and have obligatory de Sitter centre…

Electromagnetic source for the Kerr-Newman geometry

Irina Dymnikova

Source-free equations of nonlinear electrodynamics minimally coupled to gravity (NED-GR) admit regular axially symmetric asymptotically Kerr-Newman solutions, which describe electr…

Regular black hole remnants and graviatoms with de Sitter interior as heavy dark matter candidates probing inhomogeneity of early universe

Irina Dymnikova, Maxim Khlopov

We address the question of regular primordial black holes with de Sitter interior, their remnants and gravitational vacuum solitons G-lumps as heavy dark matter candidates providin…

On the higher order exterior and interior Whitehead products

Marek Golasiński, Thiago de Melo

We extend the notion of the exterior Whitehead product for maps $α_{i} : Σ A_{i} \to X_{i}$ for $i = 1, \dots, n$ , where $Σ A_{i}$ is the reduced suspension of $A_{i}$ and then, for the interior pro…

On solvable compact Clifford-Klein forms

Maciej Bochenski, Aleksy Tralle

In this article we prove that under certain assumptions, a reductive homogeneous space G/H does not admit a solvable compact Clifford-Klein form. This generalizes the well known no…

On the distance between linear codes

Mariusz Kwiatkowski, Mark Pankov

Let $V$ be an $n$ -dimensional vector space over the finite field consisting of $q$ elements and let $Γ_{k} (V)$ be the Grassmann graph formed by $k$ -dimensional subspaces of $V$ , $1…

An Overview of the 2014 ALMA Long Baseline Campaign

ALMA Partnership, E. B. Fomalont, C. Vlahakis +246

A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavel…

New constructions of symplectically fat fiber bundles

Maciej Bochenski, Anna Szczepkowska, Aleksy Tralle +1

This work is devoted to new constructions of symplectically fat fiber bundles. The latter are constructed in two ways: using the Kirwan map and expressing the fatness condition in…

Subdiagrams and invariant measures on Bratteli diagrams

M. Adamska, S. Bezuglyi, O. Karpel +1

We study ergodic finite and infinite measures defined on the path space $X_{B}$ of a Bratteli diagram $B$ which are invariant with respect to the tail equivalence relation on $X_{B}$ .…

Isometric embeddings of polar Grassmannians and metric characterizations of their apartments

Mariusz Kwiatkowski, Mark Pankov

We describe isometric embeddings of polar Grassmann graphs formed by non-maximal singular subspaces. In almost all cases, they are induced by collinearity preserving injections of…

The Shortest Path Problem for the Distant Graph of the Projective Line Over the Ring of Integers

Andrzej Matraś, Artur Siemaszko

The distant graph $G = G (P (Z), △)$ of the projective line over the ring of integers is considered. The shortest path problem in this graph is solved by use of Klein…
