Backgrounds of Two Buddha-kaya Theories

Typological Analysis of Theories and Approaches for Transect Model Backgrounds

Theory, approach and the tools of transect model have recently turned into one of the fundamental maxims of urban design and planning in the urbanization systems in Europe, the United States and more recently the middle-east, its fundamentals are based on reaching the sustainable development patterns in urban areas. A general accordance regarding the operationalizability of this theory and appr...

Little String Theories in Heterotic Backgrounds ⋆

We study Little String Theories (LST) with N = (1, 0) supersymmetry arising, in a suitable double scaling limit, from 5-branes in heterotic string theory or in the heterotic-like type II/(−) F L × shift. The limit in question, previously studied in the type II case, is such that the resulting holographically dual pairs, i.e. bulk string theory and LST can be considered to be weakly coupled. In ...

Penrose Limit and String Theories on Various Brane Backgrounds

We investigate the Penrose limit of various brane solutions including Dp-branes, NS5-branes, fundamental strings, (p, q) fivebranes and (p, q) strings. We obtain special null geodesics with the fixed radial coordinate (critical radius), along which the Penrose limit gives string theories with constant mass. We also study string theories with time-dependent mass, which arise from the Penrose lim...

Branes in Super–ads Backgrounds and Superconformal Theories

We demonstrate how actions for interacting superconformal field theories in (p+1)-dimensions arise as a result of gauge fixing worldvolume diffeomorphisms and fermionic κ-symmetry in actions for super-p-branes propagating in superbackgrounds of AdSp+2×S geometry. The method of nonlinear realizations and coset spaces is used for getting an explicit form of supervielbeins and superconnections of ...
