Recently Indian known mathematician V. Gupta introduced a general family of linear positive operators, which produces large number well-known operators as particular cases. The proposed by provides unified approach. This motivated us to extend the studies and we establish some convergence estimates include an asymptotic formula rate for function having derivatives bounded variation.

The presidential election of art and industry: the contest between Trump Biden has been staged. They have different tax, minimum wage, energy, technology, trade other strategies, which will inevitably an impact on economy United States China. Our team chose this mathematician modeling project to scientifically evaluate new president two countries, put forward our coping strategies.

The idea of the Erdös number was created by his fellow mathematicians as a humorous tribute to his enormous output as one of the most prolific modern writers of mathematical papers [1]. An Erdös number 1 is awarded to the person who has published at least one mathematical paper with the celebrated mathematician. Similarly, joint publications with someone with an Erdös number of 1 yield an Erdös...

When is a mathematical result deep? At first glance, the answer to this question is subjective: what is deep for one mathematician may not sound that deep for another. A renowned mathematician Gian-Carlo Rota expressed an opinion that the notion of deepness is more objective that we may think: namely, that a mathematical statement is deep if and only if it connects two seemingly unrelated areas...

The purpose of this work is to highlight the epistemological proximity between Nietzsche’s philosophy science and underlying philosophical principles fractal geometry, as illustrated in main its creator, French mathematician Benoit Mandelbrot.This also aims find end continuity, finding an important divergence risk taking Mandelbrot’s legacy management.

Problem 11 is due to P. E. Howard.’ The results of Problems 12 and 13 were announced by Pincus. The independence result in Theorem 7.1 1 was proved by Levy [I9621 for ZFA and transferred to Z F by Pincus [ 1969,1973b1, whose is also the observation in Problem 15.’ Example 7.12 in Section 7.4 is due to Tarski. Conditions (S) and (D) were formulated by Mostowski [1945], who proved the independenc...
