The quantization of a massless conformally coupled scalar field on the 2+1 dimensional Anti de Sitter black hole background is presented. The Green’s function is calculated, using the fact that the black hole is Anti de Sitter space with points identified, and taking into account the fact that the black hole spacetime is not globally hyperbolic. It is shown that the Green’s function calculated ...

The risk increases with the patient’s age and a reduction of certain diseases that were prevalent in the past. Surgeries for coronary artery bypass grafting are the most studied throughout the history of surgery and always presented with consistent results. The advent of angioplasty and,...

Preparation and Characterization of Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 Complexes

We have recently synthesized Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 complexes. The reaction of TiCl3(THF)3 with NaBH4 in dry THF gave flat blue crystals, Ti(BH4)3(THF)3. The reaction of VCl3 with NaBH4 in presence of N, N, N', N'- tetramethyle...
