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].

The results of the computer hunt for the primes of the form q = m + 1 up to 10 are reported. The number of sign changes of the difference πq(x) − Cq 2 ∫ x 2 du √ u log(u) and the error term for this difference is investigated. The analogs of the Brun’s constant and the Skewes number are calculated. An analog of the B conjecture of Hardy–Littlewood is formulated. It is argued that there is no Ch...

We give an effective version of a result reported by Serre asserting that the images of the Galois representations attached to an abelian surface with End(A) = Z are as large as possible for almost every prime. Our algorithm depends on the truth of Serre’s conjecture for two dimensional odd irreducible Galois representations. Assuming this conjecture we determine the finite set of primes with e...

The aim of this paper is to review the Mathematics Grammar Library (MGL) approach to multilingual mathematics and to present gfsage, a prototype of a multilingual interface to Sage. 2000 Mathematics Subject Classification. 68N18. 68T30, 68T50, 68W30.
