In this article we propose a new and so-called holomorphic deformation scheme for locally convex algebras and Hopf algebras. Essentially we regard converging power series expansion of a deformed product on a locally convex algebra, thus giving the means to actually insert complex values for the deformation parameter. Moreover we establish a topological duality theory for locally convex Hopf alg...

We describe a noncommutative deformation theory for presheaves and sheaves of modules that generalizes the commutative deformation theory of these global algebraic structures, and the noncommutative deformation theory of modules over algebras due to Laudal. In the first part of the paper, we describe a noncommutative deformation functor for presheaves of modules on a small category, and an obst...

We study a deformation of N = 4 Super-Yang-Mills theory by a dimension-5 vector operator. There is a simple nonlocal “dipole” field-theory that realizes this deformation. We present evidence that this theory is realized in the setting of “pinned-branes.” The dipoles correspond to open strings that arch out of the brane. We find the gravitational dual of the theory at large N . We also discuss t...

In a previous article (J. Algebra 367 (2012), 142-165) we established axiomatic parametrised Cohen-Macaulay approximation which in particular was applied to pairs consisting of finite type flat family rings and modules. this sequel study the induced maps deformation functors deduce properties like smoothness injectivity under general, mainly cohomological conditions on module.

A dynamical theory of hypersurface deformations is presented. It is shown that a (n+1)-dimensional space-time can be always foliated by pure deformations, governed by a non zero Hamiltonian. Quantum deformation states are defined by Schrödinger’s equation constructed with the corresponding deformation Hamiltonian operator, interpreted as the generator of the deformation diffeomorphism group.
