Generalized Baskakov-Szász type operators
Keywords: Baskakov-Szász operators Modulus of continuity Asymptotic formula Simultaneous approximation Statistical convergence Bounded variation a b s t r a c t In the present paper, we introduce generalized Baskakov-Szász type operators and study some approximation properties of these operators e.g., rate of convergence in ordinary and simultaneous approximation, statistical convergence and th...
متن کاملOtto Loewi
The end of the 19th century was the starting point of many discoveries in the field of the neurophysiology. At that time, only basic technical approaches were available, and new discoveries depended on few results and lots of deductions. Furthermore, the scientific community was often debating on theoretical speculations and was often divided. I have chosen to present a German neurophysiologist...
متن کاملModified double Szász - Mirakjan operators preserving x
In this paper, we introduce a modification of the Szász-Mirakjan type operators of two variables which preserve f0 (x, y) = 1 and f3 (x, y) = x 2 + y. We prove that this type of operators enables a better error estimation on the interval [0,∞) × [0,∞) than the classical Szász-Mirakjan type operators of two variables. Moreover, we prove a Voronovskaya-type theorem and some differential propertie...

A major emphasis of his research was refining the concept of the organizer [6], now referred to as embryonic induction [7]. He was born on 4 November 1891 in Auenstein, Germany, and came from what Viktor Hamburger [8], a colleague and personal acquaintance, described as ?peasant...
