Approximation theory and asymptotic methods form a foundational framework that bridges classical ideas with modern numerical analysis, enabling researchers to obtain practical, near‐optimal solutions ...

THE probability integral can be represented by the simple approximation over such a range (t<3) as to make the approximation useful to the statistician and others whose problems do not require great ...

We consider the functional $F(u,\Omega) = \left\{\begin{matrix} \int_{\Omega} f(x,u,Du)dx \qquad \text{if} \ u \in X = W^{1,1}_{\text{loc}}(\Omega, R^{k})\cap C^{1 ...
