  • Chaney, A.; Lu, Lei; Stern, Allen (2015-09-16)
    We show that fuzzy spheres are solutions of Lorentzian Ishibashi-Kawai-Kitazawa-Tsuchiya-type matrix models. The solutions serve as toy models of closed noncommutative cosmologies where big bang/crunch singularities appear ...
  • Stern, Allen (Elsevier, 2006-06-26)
    We write down scalar field theory and gauge theory on two-dimensional non-commutative spaces M with non-vanishing curvature and non-constant non-commutativity. Usual dynamics results upon taking the limit of M going to (i) ...
  • Pinzul, A.; Stern, Allen (Elsevier, 2005-07-11)
    We propose a procedure for computing noncommutative corrections to the metric tensor, and apply it to scalar field theory written on coordinate patches of smooth manifolds. The procedure involves finding maps to the ...
