$\varepsilon$-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.
