Stability Constants in Linear Spaces

Constructive Approximation, 2010
Let \(X\) be a linear space over the reals, \(D\subset X,\) and let \(E\) be a Banach space. A function \(f:D\to E\) is said to be \(\delta\)-Jensen if \[ \left\| f\left(\frac{x+y}{2}\right)-\frac{f(x)+f(y)}{2}\right\|\leq\delta \] whenever \(x,y,(x+y)/2\in D.\) The stability constant for Jensen equation is the infimum of those constants \(C\) for ...

Stability Constants for Courant Approximations

Journal of Mathematical Sciences, 2001
Summary: This article deals with investigation of constants of stability for the Courant approximation in metrics of spaces \(L_2\) and \(W_2^1\) in the class of triangular grids with uniformly bounded angles as well as with angles which tend to zero. In the first case numerical estimates of the Courant constants are proposed.

The stability constant of complex

The International Journal of Applied Radiation and Isotopes, 1980
Abstract The extraction of technetium in reduced valence state from aqueous perchlorate solutions with thenoyltrifluoroacetone in toluene was studied. Values of the reduced technetium partition coefficient in the presence of various concentrations of diethylenetriaminepentaacetate were measured. The dependences of the reduced technetium (labeled with
