On optimal subspaces for Kolmogorov widths of classes of 2π-periodic analytic functions
The following problem arises: to nd optimal subspaces for Kolmogorov widths of classes of convolutions with generated kernels, which may increase the oscillations.
Classes of convex polyhedra closed under Minkowski addition / Klasy wielościanów wypukłych zamknięte ze względu na dodawanie Minkowskiego
In this paper we study classes of convex polyhedra with normal vectors belonging to a given finite set G of vectors. Since a Minkowski sum A+B of two polyhedra may have normal vectors which are normal to no face of A or...

Heavy ions sputtering and implantation of surface monitored with PIXE / Rozpylanie ciężkimi jonami i implantacja powierzchni monitorowana przy pomocy PIXE
Characteristic X-rays emitted from surfaces and specially prepared thin films as a result of impact of slow heavy ions were measured and analysed. Kinematics of the interaction was simulated numerically with stopping and...
Thermodynamic properties of a Hubbard model on a cubic cluster - exact diagonalization study at quarter filling
We study the thermodynamics of a zero-dimensional, cubic cluster described with a Hubbard Hamiltonian, focusing our interest on the magnetic properties. The range in which the studied cluster is paramagnetic is considere...
