Let W be an n-dimensional Q-vector space which has a positive definite symmetric bilinear form. We prove that W is isometrically embeddable into Q n+3 . We give a formula to obtain the minimum N such that W is isometrically embeddable into Q N .
We will prove that if the predual of an injective von Neumann algebra is embedded in the predual of another von Neumann algebra almost completely isometrically, then it is complemented almost completely contractively. This result is the operator space analogue of Dor's theorem.
Let n 2, let K, K be fields such that K is a quadratic Galoisextension of K and let ฮธ denote the unique nontrivial element in Gal(K /K). Suppose the symplectic dual polar space DW (2n -1, K) is fully and isometrically embedded into the Hermitian dual polar space DH(2n -1, K , ฮธ). We prove that the p
