in this paper, we consider first-order fuzzy differential equations with initial value conditions. the convergence, consistency and stability of difference method for approximating the solution of fuzzy differential equations involving generalized h-differentiability, are studied. then the local truncation error is defined and sufficient conditions for convergence, consistency and stability of ...

the acidity constants of some amino acids (am) were determined by potentiometric ph titration. the stability constants of the 1:1 complexes formed between m2+: ca2+, mg2+, mn2+, co2+, ni2+, cu2+ or zn2+ and am2-, were determined by potentiometric ph titration in aqueous solution (i = 0.1 m, nano3, 25°c). the order of the stability constants was reported. it is shown that the stability of the bi...

In this paper we study the class of differential variational inequality(DVI) in a finite-dimension Euclidean space <n, which is the following form ẋ(t) = f(t, x(t)) + B(t, x(t))u(t) , x(0) = x0 ∈ <n 0 ≤ (ũ− u(t))T [G(t, x(t)) + F (u(t))] for almost all ũ ∈ K u(t) ∈ K We study stability and perturbation of the DVI under the OSL condition. Besides, we establish a Prior Bound Theorem, which is a u...

In this note we investigate the stability of game theoretic and economic solution concepts under input perturbations. The existence of many of these solutions is proved using fixed point theorems. We note that fixed point theorems, in general, do not provide stable solutions, and we show how some commonly studied solution concepts are indeed not stable under perturbation of the inputs.
