초록

In this paper, we extend the notion of comonotone approximation to linear 2-normed spaces. We shall study comonotone approximation of finite dimensional linear 2-normed spaces in the sense of simultaneous and best si-multaneous approximation. We give and prove some results and theorems on characterization and uniqueness of comonotone approximation. In this spaces,our results coincide with the usual one.
