**proved**for closed linear manifolds in L2 [ 0 , 1 ] by E. Fischer [ 2 ] . The fact that a linear manifold which is not dense in the entire space has a non - zero orthogonal complement (**proved**in ...Page 385

**proved**that in the case of a separable space these notions coincide with that of closure in the X topology of X * . Alaoglu ( 1 ; p . 256 ] and Kakutani [ 2 ; p . 170 ] independently established the equivalence of these types ...### What people are saying - Write a review
