We prove that for every finite dimensional compact metric space X there is an open continuous linear surjection from Cp[0, 1] onto Cp(X). The proof makes use of embeddings introduced by Kolmogorov and Sternfeld in connection with Hilbert’s

We review some theoretical and experimental issues in unparticle physics, focusing mainly on collider signatures.

We present an octonionic N = 1 superfield action that reproduces in components the action of Bagger and Lambert for M2 branes. By giving an expectation value to one of the scalars we obtain the maximally supersymmetric superfield action for D2 branes.

We present a partial characterization of matrices in Mn(A) + satisfying the Størmer condition. Mathematical Subject Classification: Primary: 46L55 Secondary: 46L05
