But perhaps the crucial factor has been the continuing presence of its main practitioner, Jacques Derrida, who refused, one might say, to become part of history. Right up to his death in October of 2004, Derrida wrote about some of the key issues facing the world today. So while deconstruction as a ‘‘theory’’ has lar...

We demonstrate a dynamical origin for the dimension-five seesaw operator in dimensional deconstruction models. Light neutrino masses arise from the seesaw scale which corresponds to the inverse lattice spacing. It is shown that the deconstructing limit naturally prefers maximal leptonic mixing. Higher-order corrections which are allowed by gauge invariance can transform the bimaximal into a bil...

We present evidence that N = 1 * SUSY Yang-Mills provides a decon-struction of a six-dimensional gauge theory compactified on a two-sphere. The six-dimensional theory is a twisted compactification of N = (1, 1) SUSY Yang-Mills theory of the type considered by Maldacena and Nunez (MN) in [1]. In particular, we calculate the full classical spectrum of the N = 1 * theory with gauge group U (N) in ...

In this paper we propose a quiver model of matrix quantum mechanics with 8 supercharges which, on a Higgs branch, deconstructs the worldsheet of Matrix String Theory. This discrete model evades the fermion doubling problem and, in the continuum limit, enhances the number of supersymmetries to sixteen. Our model is motivated by orbifolding the Matrix Model, and the deconstruction ansatz exhibits...

Running of gauge couplings on a slice of AdS5 is examined using the deconstruction setup. Logarithmic running instead of (linear) power law is justified when the cutoff is lower than the curvature scale. Most of interesting features including the localization of Kaluza-Klein modes and the widening of higher Kaluza-Klein spectrum spacing are well captured within the framework of deconstruction. ...
