The purpose of this note is to answer the question whether the Â-genus vanishes on S-manifolds with finite second homotopy group… (More)

The Atiyah-Singer index theorem is investigated on various compact manifolds which admit finite matrix approximations (“fuzzy… (More)

We study a membrane – anti-membrane system in Matrix theory. It in fact exhibits the tachyon instability. By suitably… (More)

Partial dynamical symmetry describes a situation in which some eigenstates have a symmetry which the quantum Hamiltonian does not… (More)

We consider the problem of representing in Hilbert space commutation relations of the form a i a * j = δ ij 1 + kℓ T kℓ ij a… (More)
