On the Constant in The Lower Estimate for the Bernstein Operator
Sorin Gal, Gancho Tachev
For functions belonging to the classes and , we establish the lower estimate with an explicit constant in approximation by Bernstein polynomials in terms…
On Some Geometric Properties of Slice Regular Functions of a Quaternion Variable
Sorin G. Gal, J. Oscar González-Cervantes, Irene Sabadini
The goal of this paper is to introduce and study some geometric properties of slice regular functions of quaternion variable like univalence, subordination, starlikeness, convexity…
On the Kurzweil-Henstock integral in probability
Sorin G. Gal
By using the method in [5], the aim of the present note is to generalize the Riemann integral in probability introduced in [7], to Kurzweil-Henstock integral in probability. Proper…
On an identity derived from interpolation theory
Sorin G. Gal
The aim of this short note is to show how can be derived from the properties of fundamental interpolation polynomials some nice identities.
Linear continuous functionals on FN-type spaces
Sorin G. Gal
By using the space of fuzzy numbers, in e.g. [5] have been considered several complete metric spaces (called here {\bf FN}-type spaces) endowed with addition and scalar multiplicat…
Approximation by Choquet Integral Operators
Sorin G Gal
The main aim of this paper is to show that the nonlinear Choquet integral can be used to construct nonlinear approximation operators, exactly as by the use in probability of the Le…
