Univariate Shepard operators combined with least squares fitting polynomials
Abstract We obtain new univariate Shepard operators using polynomials that are constructed such that they fit the interpolation data in…
On the pointwise convergence of a family of functionals on C(I)
Abstract Given a continuous function \(u:[0,\infty)\rightarrow \mathbb{R}\), a family of functionals \(\varphi_{\U{3b1} }:C(I)\rightarrow \mathbb{R},\U{3b1} >0,\) is defined by \(\varphi_{\U{3b1} }(f)=\frac{1}{\U{3b1}…
The photogravitational model of Constantin Popovici in a Manev-type field
Abstract The photogravitational model of Constantin Popovici combines the Newtonian attraction force with a radiative repelling one. We consider a…
Two and three-dimensional inverse problem of dynamics
Abstract For a given a monoparametric family of curves \(f(x,y)=c\), we present the partial differential equations satisfied by the potentials…
Properties of the complexity function for finite words
Abstract The subword complexity function \(p_{w}\) of a finite word \(w\) over a finite alphabet A with card \(A=q\geq1\) is…
An estimation of a generalized divided difference in uniformly convex spaces
Abstract The rest in some approximation formulae can be expressed in terms of a generalized divided di§erence on three knots.…
Strong forces in Celestial Mechanics
Abstract Strong forces in celestial mechanics have the property that the particle moving under their action can describe periodic orbits,…
Symmetries in the Popovici-Manev photogravitational field
Abstract The Popovici-Manev photogravitational field is generated by a Manev-type attraction force and the repelling radiative force considered by Constantin…
Symmetric periodic orbits in the anisotropic Schwarzschild-type problem
Abstract Studying the two-body problem associated to an anisotropic Schwarzschild-type field, Mioc et al. (2003) did not succeed in proving…
