$\varepsilon$-approximation in generalized 2-normed spaces
Mehmet Aç\i kgöz

Abstract

The notion of generalized 2-normed spaces was introduced by Lewandowska in 1999~[5]. One can obtain a generalized 2-normed space from a normed space. We shall define the notions of 1-type $\varepsilon$-quasi Chebyshev subspaces and give some results in this field.
