Some Results on p-Best Approximation in Vector Spaces

Beyond the perturbed static path approximation (PSPA)

Based on the path integral approach the partition function of a many body system with separable two body interaction is calculated in the sense of a semiclassical approximation. The commonly used Gaussian type of approximation, known as the perturbed static path approximation (PSPA), breaks down near a crossover temperature due to instabilities of the classical mean field solution. It is shown ...

The nucleon-nucleon potential beyond the static approximation

Deptartament d’Estructura i Constituents de la Matèria, Universitat de Barcelona Diagonal 647, 08028 Barcelona, Catalonia, Spain Abstract We point out that, due to the use of static nucleon propagators in Heavy Baryon Chiral Perturbation Theory, the current calculations of the nucleon-nucleon potential miss certain contributions starting at two loops. These contributions give rise to contact in...

SOME RESULTS ON t-BEST APPROXIMATION IN FUZZY n-NORMED SPACES

The aim of this paper is to give the set of all t -best approximations on fuzzy n-normed spaces and prove some theorems in the sense of Vaezpour and Karimi [13].
