Catalysis of Black Holes/Wormholes Formation in High Energy Collisions
I. Ya. Aref'eva
We discuss various mechanisms of catalysis of black holes/wormholes (BH/WH) formation in particles collisions. The current paradigm suggests that BH/WH formation in particles colli…
Parametrisations of elements of spinor and orthogonal groups using exterior exponents
Nikolay Marchuk
We present new parametrizations of elements of spinor and orthogonal groups of dimension 4 using Grassmann exterior algebra. Theory of spinor groups is an important tool in theoret…
Schur rings over a product of Galois rings
Sergei Evdokimov, Ilya Ponomarenko
The recently developed theory of Schur rings over a finite cyclic group is generalized to Schur rings over a ring R being a product of Galois rings of coprime characteristics. It i…
Jordanian deformation of the open XXX-spin chain
P. P. Kulish, N. Manojlovic, Z. Nagy
The general solution to the reflection equation associated with the jordanian deformation of the SL(2) invariant Yang R-matrix is found. The same K-matrix is obtained by the specia…
Integrable systems and local fields
A. N. Parshin
In 70's there was discovered a construction how to attach to some algebraic-geometric data an infinite-dimensional subspace in the space k((z)) of the Laurent power series. The con…
On the Stokes problem with non-zero divergence
Nikolay Filonov, Tim Shilkin
We study the strong solvability of the nonstationary Stokes problem with non-zero divergence in a bounded domain.
