Quasicrystallographic groups on Minkowski spaces
Siberian Mathematical Journal, 2009Summary: We generalize the quasicrystallographic groups in the sense of Novikov and Veselov from Euclidean spaces to pseudo-Euclidean and affine spaces. We prove that the quasicrystallographic groups on Minkowski spaces whose rotation groups satisfy an additional assumption are projections of crystallographic groups on pseudo-Euclidean spaces.

The purpose of this paper is to prove one of Zeeman's conjectures that the group of homeomorphisms of the finest topology on Minkowski space that induces the 3-dimensional Euclidean topology on spacelike hyperplanes is the one generated by the inhomogeneous Lorentz group and dilatations.

The concept of symmetry groups has a mathematically well defined generalization in the framework of Hopf algebras. Such generalizations have become known as quantum groups- these are Hopf algebras with an algebraic structure which depends on one or more parameters q (q ∊ C,q ≠ 0), such that for a particular value of these parameters, say q = 1, the ...

PLATEAU'S PROBLEM IN MINKOWSKI SPACE
Analysis, 1985The author proves that any spacelike immersion of \(S^{n-2}\) into the n- dimensional Minkowski space which admits some spacelike extension to the unit ball \(B\subset {\mathbb{R}}^{n-1}\) is the boundary of a maximal (with respect to the induced metric) spacelike immersion of B. In the case \(n=3\) it is shown that such a maximal surface is in general
