Base subsets of polar Grassmannians

Mark Pankov

Let $Δ$ be a thick building of type $X_{n} = C_{n}, D_{n}$ . Let also $G_{k}$ be the Grassmannian of $k$ -dimensional singular subspaces of the assoc…

Exotic smooth structures and symplectic forms on closed manifolds

Boguslaw Hajduk, Aleksy Tralle

We give a short proof of the (known) result that there are no Kaehler structures on exotic tori. This yields a negative solution to a problem posed by Benson and Gordon. W discuss…

Spinning superconducting electrovacuum soliton

Irina Dymnikova

In nonlinear electrodynamics coupled to general relativity and satisfying the weak energy condition, a spherically symmetric electrically charged electrovacuum soliton has obligato…

Gauge-noninvariance of quantum cosmology and vacuum dark energy

Irina Dymnikova, Michael Fil'chenkov

We address the question how to adapt cosmological constant $Λ$ for description of a vacuum dark energy density jumping from the big initial value to the small today value suggested…

Order preserving transformations of the Hilbert grassmannian

Mark Pankov

Let $H$ be a separable real Hilbert space. Denote by $G_{\infty} (H)$ the Grassmannian consisting of closed subspaces with infinite dimension and codimension. This Grassm…

Base subsets of symplectic Grassmannians

Mark Pankov

Let $V$ and $V^{'}$ be $2 n$ -dimensional vector spaces over fields $F$ and $F^{'}$ . Let also $Ω : V \times V \to F$ and $Ω^{'} : V^{'} \times V^{'} \to F^{'}$ be non-degenerate symplectic forms. Denote by…

The B-quadrilateral lattice, its transformations and the algebro-geometric construction

Adam Doliwa

The B-quadrilateral lattice (BQL) provides geometric interpretation of Miwa's discrete BKP equation within the quadrialteral lattice (QL) theory. After discussing the projective-ge…
