Wraz z reformą emerytalną z roku 1999 zmienił się zasadniczo sposób naliczania wysokości emerytury. Emeryturę E nalicza się według prostego wzoru: E=K/T, gdzie K jest sumą zwaloryzowanych składek emerytalnych oraz ...

Maxima CAS(*) script for the chaos game simulation along a deterministic driver, e.g., de Bruijn sequence. Under suitable assumptions chaos game algorithm recovers a semiattractor of an iterated function system (IFS). [(*) ...

We study the composition of irreducible morphisms between indecomposable modules lying in quasi-tubes of the Auslander-Reiten quivers of artin algebras in relation with the powers of the radical of their module category.

Average path length is recognised as one of the vital characteristics of random graphs and complex networks. Despite a rather sparse structure, some cases were reported to have a relatively short lengths between every pair ...

In this paper we study ergodic properties of the Poisson suspension (the ideal gas model) of the billiard flow $(b_t)_{t\in\mathbb R}$ on the plane with a $\Lambda$-periodic pattern ($\Lambda\subset\mathbb R^2$ is a lattice) ...

We determine the Krull dimension of the module category of finite dimensional tame generalized multicoil algebras over an algebraically closed field, which are domestic.

We classify, up to derived (equivalently, tilting-cotilting) equivalence all nondegenerate gentle two-cycle algebras. We also give a partial classification and formulate a conjecture in the degenerate case.
