In this paper, A.B.Mingarellis result is generalized to General Volterra-Stieltjes Integro-differential Equations. Comparison theorem and equivalence condition
Let Bn be the unit ball in Cn, we study quasi-convex mappings and starlike mappings on Bn. The upper bounds of second order item coefficients ofr quasi-convex m
The famous conjecture in distribution of prime numbers remains unsolved whether there exists a constant inequality of “π(x+y)≤π(x)+π(y)” for all integers
