WebExplain how string theory appears to solve these problems. 2. Use the language of string theory (strings, branes, etc.) to describe how string theory relates different numbers of dimensions of space-time to our familiar 3-D world. 3. Contrast string theory with other branches and theories of physics in terms of Web1 day ago · We show that vanishing of the sigma-model beta-functions for the metric g μ ν, antisymmetric tensor B μ ν and dilaton Φ of any string-theory model in D dimensions at tree level can be obtained from a universal effective action, provided that the field combination − g e − 2 Φ is non-dynamical. The central-charge deficit term is omitted from the action and …
