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 ... -
Własności prawdopodobieństwa błędnie sugerowane przez prawdopodobieństwo klasyczne
(2002)The test discussed in this paper is a specific set of problems used to asses certain competences in the domain of the probability theory and in the domain of logic. The content of each problem placed in this test verifies ... -
Nietendencyjność losowania metodą „marynarza* jako problem stochastyczny
(2002)The main objective of this paper is the answer to the question: „Is using the „sailor” method fair, when choosing a random person?” In this method, at the appointed sign, each participant n sticks out 1 to 5 fingers of ... -
Osobliwe własności modeli probabilistycznych czekania na serie sukcesów i porażek
(2002)This paper concerns, specific, not well known but simultaneously elementary means of argumentation used in the process of constructing probabilistic spaces and calculating the probability in those spaces. The above ...
