Solutions to a certain problem illustrating the idea of fusionism in the probability theory
(2003)The solutions presented above may serve as an illustration of "the principle of internal integration”, known as the idea of liisionisiii. Three balls are selected simultaneously from an urn containing b white balls and ... -
Awaiting the series of colors - stochastic graph as a means of mathematical treatment and argumentation
(2003)This paper presents methods of calculating the probability of events related to Markov’s homogeneous chains theory. The main means of argumentation being the stochastic graph. -
On new differential equations of the first order in the space $M(1,4) x R(u)$ with non-trivial symmetries
(2003)Some new differential equations of the first order in the space $M(1,4) x R(u)$, which are invariant under splitting subgroups of the generalized Poincaré group $P(1,4)$ are presented. -
A proof of S. Rolewicz's conjecture
(2002)S. Rolewicz’s conjecture concerning solutions of the functional-differential inequality (P) is proved. -
Wpływ uporządkowania magnetycznego na dynamikę sieci wybranych trójskładnikowych dichalkogenków metali przejściowych
(2019-09-10)Badania z pierwszych zasad oparte o teorie funkcjonału gęstości DFT podjęto w celu wyznaczenia właściwości dynamicznych trójskładnikowych, warstwowych dwuselenków metali przejściowych KNi[2]Se[2] [A1], KCo[2]Se[2] [A2] ... -
Sur quelques problèmes ouverts
(2001)On pose les problèmes au sujet de la raréfaction des ensembles, des prolongements de la mesure de Jordan et des homomorphismes, de la stabilité de l’équation de translation, de la décomposition des fonctions et sur les ... -
Sur les généralisations du wronskien
(2001)En généralisant le wronskien on montre que l’évanouissement de ce wronskien est équivalent à la dépendance linéaire du système des fonc tions. Le théorème analogue est donné pour la décomposition d’une fonc tion $h(x, y)$ ... -
General continuous solution of a nonlinear functional inequality
(2001)In this paper we present theorems on the existence of continuous solutions of the functional inequality (1) in the case where the continuous solution of the corresponding functional equation (2) is not unique. -
Ternary semigroups of linear mappings and matrices
(2001)Following the classical Green’s equivalences we examine, by means of some equivalence relations, the structure of the ternary semigroup of linear mappings. The suitable results for the ternary semigroup of matrices are ... -
Wpływ niestechiometrii na zmiany czasowe i temperaturowe prądu depolaryzacji ceramiki niobianu sodu
(1986)Time and temperature changes of polarisation and depolarisation currents of the $NaNbO_3$ ceramics samples assumed to have correct stoichiometric content and of the samples $NaNbO_3$ having the excess of niobium or sodium ... -
Zjawiska fotoelektryczne w monokryształach BaTiO[3] w obszarze niskotemperaturowych przejść fazowych
(1986)This work concerns ferroelectric phenomena in monocrystals BaTiO[3]. Influence of light illumination on electric conductivity and on phase transition temperature was studied in particular. It was found that illumination ... -
Wpływ stałego pola elektrycznego i magnetycznego na zmiany temperaturowe przenikalności elektrycznej w BaTiO[3]
(1986)Influence of the constant electric field on temperature changes of electric permeability in BaTiO[3] were studied. It was found that the Curie temperature shifts towards higher value and that the value of max decreases ... -
Urządzenie do mierzenia fotoindukowanej luminescencji
(1986)The construction of a simple device for measurements of photoinduced, slowly decaying luminescence from biological samples is described. Construction elements and subsystems available at the domestic market are mainly ... -
Zmiany temperaturowe współczynnika przewodnictwa ciepła niobianu sodu
(1986)Construction of the vacuum thermostat intended for measuring the heat conductivity of ferroelectrics and its temperature changes is presented. The properties of $NaNbO_3$ are studied in order to apply it in building the ...
