Let (X;‖ ‖) be a Banach space. By B(X) we denote the set of all bounded linear operators in X. Let C∈B(X) be injective.A strongly continuous family of bounded operators {S(t); t≥0} is called an exponentially bound...
It is well known that rare earth metals consist of 17 elements including the lanthanoid series (Z=57-71) of the Periodic Table, and Sc and Y. The structure of the electron shells and atomic nuclei of the rare earths a...
It is necessary to solve the nonlinear equations of fluid dynamics as unsteady problems as far as numerical weather prediction problems are concerned, and nonlinear computational instability often occurs when explicit...
According to S. Smale, an algorithm is said to be tractable if its cost of finding a zero of a complex polynomial does not grow exponentially with the degree of polynomials. Smale proved that for the case all |c_k|<1,...
