Generalization of Einstein's Relativity Two Dimensional Approach

Authors: Saurav Dwivedi
Comments: Pages.

Einstein’s (General and Special) relativity has been described in four-dimensional space (Minkovskian space) by four-coordinates under Lorentz transformation. However, the analysis is useful in modern physics but yet non-generalized. Moreover, generalization of relativity would not be possible with simple (any way if four) coordinates because it despite generalized coordinates. In this manner of description, ‘generalized relativity’ would be formulated in two-dimensional space under a new ‘generalized space-time geometry’ under two-dimensional generalized transformation. However, in generalization of Relativity, its epistemology and paradoxical cases remain unchanged. They would only be modified under new scheme with two-dimensional description instead of four. Reference frame observability has unchanged epistemology under such schemes. However, the procedure for choosing coordinates, with despite of generalized coordinates, is modified.

4D Quantum Gravity via W_infinity Gauge Theories in 2D, Collective Fields and Matrix Models

Authors: Carlos Castro
Comments: recovered from sciprint.org

It is shown how Quantum Gravity in D = 3 can be described by a W_inifnity Matrix Model in D = 1 that can be solved exactly via the Collective Field Theory method. A quantization of 4D Gravity can be attained via a 2D Quantum W_inifnity gauge theory coupled to an infinite-component scalar-multiplet ; i.e. the quantization of Einstein Gravity in 4D admits a reformulation in terms of a 2D Quantum W_inifnity gauge theory coupled to an infinite family of scalar fields. Since higher-spin W_inifnity symmetries are very relevant in the study of 2D W_inifnity Gravity, the Quantum Hall effect, large N QCD, strings, membranes, topological QFT, gravitational instantons, Noncommutative 4D Gravity, Modular Matrix Models and the Monster group, it is warranted to explore further the interplay among all these theories.
