Interacting Spinors-Scalars and AdS/CFT Correspondence
By taking the interacting spinor-scalar theory on the space we
calculate the boundary CFT correlation functions using AdS/CFT correspondence.Comment: The crucial role of the surface term in the action to generate the
correlation functions quadratic in spinors is considered. LaTeX file, 8 page
From Dimensional Reduction of 4d Spin Foam Model to Adding Non-Gravitational Fields to 3d Spin Foam Model
A Kaluza-Klein like approach for a 4d spin foam model is considered. By
applying this approach to a model based on group field theory in 4d (TOCY
model), and using the Peter-Weyl expansion of the gravitational field,
reconstruction of new non gravitational fields and interactions in the action
are found. The perturbative expansion of the partition function produces graphs
colored with su(2) algebraic data, from which one can reconstruct a 3d
simplicial complex representing space-time and its geometry; (like in the
Ponzano-Regge formulation of pure 3d quantum gravity), as well as the Feynman
graph for typical matter fields. Thus a mechanism for generation of matter and
construction of new dimensions are found from pure gravity.Comment: 11 pages, no figure, to be published in International Journal of

Quantizing field theories in noncommutative geometry and the correspondence between anti de Sitter space and conformal field theory
By using the approach of non-commutative geometry, we study spinors and
scalars on the two layers AdS space. We have found that in the boundary
of two layers AdS space, by using the AdS/CFT correspondence, we have a
logarithmic conformal field theory. This observation propose a way to get the
quantum field theory in the context of non-commutative geometry.Comment: some minor typographical errors are corrected, to appear in Phys.

M-Branes and Their Interactions in Static Matrix Model
Different BPS M-brane configurations including single and two parallel
M-branes (= even) and M5-branes are introduced as the classical solutions
of the recently proposed Static Matrix Model. Also the long range interactions
of two relatively rotated M-branes (one and two angles) and
M-brane--anti-M-brane are calculated. The results are in agreement with
11 dimensional supergravity results.Comment: Latex file, 17 pages, No Figure
