One-complemented subspaces of Musielak-Orlicz sequence spaces

摘要

The aim of this paper is to characterize one-complemented subspaces of finite codimension in the Musielak-Orlicz sequence space to. We generalize the well-known fact (Ann. Mat. Pura Appl. 152 (1988) 53; Period. Math. Hungar. 22 (1991) 16 1; Classical Banach Spaces 1, Springer, Berlin, 1977) that a subspace of finite codimension in l(p), 1less than or equal top
