Seshadri fibrations on algebraic surfaces
(2004)We show that small Seshadri constants in a general point of a surface have strong geometrical implications, the surface is fibered by curves computing the Seshadri constant. We give a sharp bound in terms of the ... -
Seshadri constants of unisecant line bundles on ruled surfaces
(2004)The aim of this paper is to show that for any ruled surface $X$ with a unisecant polarization $L ≡ C_0 + μ_0f$ the Seshadri constant of $L$ at every point of $X$ is equal $1$. -
Local analytic solutions of a functional equation
(2004)All analytic solutions of the functional equation \[|f(r exp(iθ))|^2 + |f(1)|^2 = |f(r)|^2 + |f(exp(iθ))|^2\] in the annulus \[P := {z ∈ C : 1 − ε < |z| < 1 + ε}\] and in the domain \[D := {z = re^{iθ} ∈ C : ... -
On the rate of convergence theorem for the alternate Poisson integrals for Hermite and Laguerre expansions
(2004)The aim of this paper is the study of a rate of convergence of alternate Poisson integrals for Hermite and Laguerre expansions. We state some estimates of the rate of convergence of these integrals using the classical ... -
On the differential first-order invariants for the non-splitting subgroups of the generalized Poincare group P(1,4)
(2004)The functional bases of the differential first-order invariants for all non-splitting subgroups of the generalized Poincaré group P(1, 4) are constructed. Some applications of the results obtained are considered. -
On some functional equations related to Steffensen's inequality
(2004)We consider the problem, proposed by the second author (cf. [1]) of solving functional equations stemming from the Steffensen integral inequality (S), which is applicable in actuarial problems, cf. [4]. Imposing some ... -
Kalkulatory graficzne i komputery a testy istotności
(2002)In the first part of this paper we show how to determine, using a CASIO graphic calculator, the power of a significance test. The suitable programmes, prepared by the author, are attached in the annex. In the second part ... -
Symetrie a proces matematyzacji, rachunki i dedukcja w rachunku prawdopodobieństwa
(2002)This paper deals with symmetry as a specific mathematical means (constructing probabilistic models of certain statistical experiments) and device in the organisation of the calculation phase of a solution and deduction ...
