We investigate the AdS/CFT correspondence for higher-derivative gravity systems, and develop a formalism in which the generating functional of the boundary field theory is given as a functional that depends only on the boundary values of bulk fields. We also derive a Hamilton-Jacobi-like equation that uniquely determines the generating functional, and give an algorithm calculating the Weyl anom...

Gravitational axial and chiral anomalies in a noncommutative space are examined through the explicit perturbative computation of one-loop diagrams in various dimensions. The analysis depend on how gravity is coupled to noncommutative matter fields. DelbourgoSalam computation of the gravitational axial anomaly contribution to the pion decay into two photons, is studied in detail in this context....

The “parity” anomaly – more accurately described as an anomaly in time-reversal or reflection symmetry – arises in certain theories of fermions coupled to gauge fields and/or gravity in a spacetime of odd dimension. This anomaly has traditionally been studied on orientable manifolds only, but recent developments involving topological superconductors have made it clear that one can get more info...

We propose a lattice formulation of the chiral fermion which maximally respects the gauge symmetry and simultaneously is free of the unwanted species doublers. This is achieved by directly dealing with the lattice fermion propagator and the composite operators, rather than the lattice action and the fermionic determinant. The latter is defined as a functional integral of the expectation value o...

Temperomandibular joint ankylosis is a relatively common anomaly affecting the face causing facial asymmetry which necessitates multiple surgeries to restore function and form to near normal. The most important diagnostic aid in T.M.J ankylosis is radiography ranging from conventional radiography to C.T scans. This is a case report of an unusual radiographic presentation of bilateral T.M.J anky...

We illustrate the Dirichlet prescription of the AdS/CFT correspondence using the example of a massive scalar field and argue that it is the only entirely consistent regularization procedure known so far. Using the Dirichlet prescription, we then calculate the divergent terms for gravity in the cases d = 2, 4, 6, which give rise to the Weyl anomaly in the boundary conformal field theory. E-mail:...
