    On Finite Dimensional 2-Normed Spaces
    (2016-02-17) Gunawan, Hendra; Mashadi
    In this note we shall study nite dimensional 􀀀 normed spaces and show that their topology can be fully described by using a certain norm derived from the 􀀀 norm Moreover we show that a 􀀀 Banach space is a Banach space and use this fact to prove the Fixed Point Theorem Our result extends to some in nite dimensional 􀀀 normed spaces

    Orthogonality In 2-Normed Spaces Revisited
    (2016-02-17) Gunawan, Hendra; Mashadi; Gemawati, Sri; Nursupiamin; Sihwaningrum, Idha
    In this paper we discuss some existing notions of orthogonality in 2-normed spaces and their drawback. We also formulate new de¯nitions of orthogo- nality that improve the existing ones. In the standard 2-normed space, our notions of orthogonality coincide with the usual one.
