As was the case in the parent 10-dimensional theory, 9-dimensional N = 1 supergravity contains a single supergravity multiplet and an arbitrary number of vector multiplets.

The field G _ 0 however does not arise from the dimensional reduction, massive IIA is not known to be the dimensional reduction of any higher-dimensional theory.
33.
From 1918 until 1923, there were three distinct approaches to field theory : the gauge theory of Weyl, Kaluza's five-dimensional theory, and Eddington's development of affine geometry.
34.
N . B . : Here, a symmetry is said to be local or global from the two dimensional theory ( on the worldsheet ) point of view.
35.
This led to the realization, in the mid-1990s, that all of the five consistent superstring theories are just different limiting cases of a single eleven-dimensional theory called M-theory.
36.
Compactifying on a more general Calabi-Yau sixfold, 3 / 4 of the supersymmetry is removed to yield a four-dimensional theory with 8 real supercharges ( N = 2 ).
37.
Firstly, four-dimensional accounts of time are argued to better explain paradoxes of change over time ( often referred to as the paradox of the Ship of Theseus ) than three-dimensional theories.
38.
The Riemann mapping theorem about the conformal relationship of certain domains in the complex plane, which may be the most important result in the one-dimensional theory, fails dramatically in higher dimensions.
39.
Beginning in the mid-1880s, Motora translated the new theories of Western psychology such as the James Lange theory and Wilhelm Wundt's three-dimensional theory of feelings for publication in Japan.
40.
Further, in a much simpler fashion one may consider a model with only one extra dimension ( a type of Kaluza Klein model ) and compactify down to a four-dimensional theory.
