Generalized convex sets
(1997)In this paper we shall present a definition of convex set with respect to a two-parameter family of functions. It appears that these sets have some properties like convex sets in the usual sense. -
On the convergence of singular integrals of vector-valued functions
(1997)The pointwise convergence of abstract singular convolution integrals K(•,v) * f (x - •) depending on two parameters x,v (x ϵ R, v belongs to a metric space E) is studied. The convergence of the parameters is restricted to ... -
Remarks on real-valued quasi-isometries
(1997)In this paper we consider the class of solutions of the functional inequality | |f(x) - f( y)| - |x – y| | ≤ ε ϵ min{|f(x) - f(y)|,|x - y|}, x, y ϵ R where f : IR -> IR is the unknown function and ε ϵ [0,1). The two ... -
On bounded solutions of a generalized Schilling's problem
(1997)In this note we prove that, under some assumptions on a, b, c, h, g and Q, the zero function is the only solution φ : R → R of the functional equation φ(g(x)) = a(x)φ(h(x)) + b(x)φ(h[-1](x)) + c(x)φ(x), bounded in a ... -
Singular solutions of some nonlinear singular partial differential equations
(1997)In this paper a family of formal solutions of the Laplace-Beltrami equation is constructed and the convergence of these formal series is proved by finding the majorant convergent series. -
Badanie zależności między właściwym przewodnictwem elektrycznym opadu a temperaturą opadu
(1996)The quality of rainfall is determined by many parameters. Generally, these parameters can be divided into four groups. To the first group we can include parameters associated to antropogenic activity. The parameters of ... -
Analiza jonowa pojedynczego opadu
(1996)The ion composition of subsequent millimeters of atmospheric precipitation of September 15, 1995 in a single locality at Podchorążych Street (Table 1) was determined. During 650 minutes 36 mm of atmospheric precipitation ...
