چکیده
A Lorentz and general co-ordinate co-variant form of canonical gravity, using Ashtekar’s variables, is investigated. A co-variant treatment due to Crnkovic and Witten is used, in which a point in phase space represents a solution of the equations of motion and a symplectic functional two form is constructed which is Lorentz and general co-ordinate invariant. The subtleties and difficulties due to the complex nature of Ashtekar’s variables are addressed and resolved. PACS Nos. 04.20.Cv 04.20.Fy

متن کاملTowards a Background Independent Quantum Gravity in Eight Dimensions
We start a program of background independent quantum gravity in eight dimensions. We begin by considering canonical gravity a la ”Kaluza-Klein” in D = d + 1 dimensions. We show that our canonical gravity approach can be applied to the case of self-dual gravity in four dimensions. Further, by using our previously proposed classical action of Ashtekar self-dual gravity formalism in eight dimensio...

We study numerically the dynamical triangulation formulation of two-dimensional quantum gravity using a restricted class of triangulation, so-called minimal triangulations, in which only vertices of coordination number 5, 6, and 7 are allowed [1]. A real-space RG analysis shows that for pure gravity (central charge c = 0) this restriction does not affect the critical behavior of the model. Furt...

We introduce a graphical representation for a global SO(n) tensor ∂μ∂νhαβ , which generally appears in the perturbative approach of gravity around the flat space: gμν = δμν + hμν . We systematically construct global SO(n) invariants. Independence and completeness of those invariants are shown by taking examples of ∂∂h-, and (∂∂h)invariants. They are classified graphically. Indices which charact...

We investigate thermalization processes occurring at different time scales in the Yang-Mills-Higgs system at high temperatures. We determine the largest Lyapunov exponent associated with the gauge fields and verify its relation to the perturbatively calculated damping rate of a static gauge boson.
