On the Hodge decomposition in R^n
We prove a version of the hodge decomposition for differential forms in
Euclidean space and a generalization to the class of Lizorkin currents. We also
compute the cohomology of .Comment: 28 page
On the origin of Hilbert Geometry
In this brief essay we succinctly comment on the historical origin of Hilbert
geometry. In particular, we give a summary of the letter in which David Hilbert
informs his friend and colleague Felix Klein about his discovery of this
geometry. The present paper is to appear in the Handbook of Hilbert geometry,

On the Moduli Space of Singular Euclidean Surfaces
The goal of this paper is to develop some aspects of the deformation theory
of piecewise flat structures on surfaces and use this theory to construct new
geometric structures on the moduli space of Riemann surfaces.Comment: To appear in the Handbook of Teichmuller Theory, vol. 1, ed. A.

Modelling of heat treatment of plates from aluminum alloys using ESI group solution for heat treatment
To produce competitive high quality product with reducing manufacturing cost more and more companies make a choice of using numerical simulations as the first manufacturing step. Virtual manufacturing solution from ESI Group helps users to find the best way of organization manufacturing process, to avoid mistakes in real life, evaluated them during simulation processes
The Myers-Steenrod theorem for Finsler manifolds of low regularity
We prove a version of Myers-Steenrod's theorem for Finsler manifolds under
minimal regularity hypothesis. In particular we show that an isometry between
-smooth (or partially smooth) Finsler metrics, with ,
, and is necessary a
diffeomorphism of class . A generalisation of this result to
the case of Finsler 1-quasiconformal mapping is given. The proofs are based on
the reduction of the Finlserian problems to Riemannian ones with the help of
the the Binet-Legendre metric.Comment: 14 page
