In the mid-1970s, physicists began studying higher-dimensional theories combining general relativity with supersymmetry, the so-called supergravity theories.

Robert Plutchik offers a three-dimensional model that is a hybrid of both basic-complex categories and dimensional theories.
13.
This 11-dimensional theory is known as M-theory.
14.
And the five 10-dimensional theories turned out to be just different views of a single underlying 11-dimensional theory.

16.
The existence of these superstring theories are just different limiting cases of a single eleven-dimensional theory called M-theory.
17.
This was the first of the extra dimensional theories, which later came to be known as Kaluza Klein theory.
18.
In extended 4-dimensional theories with N = 2 supersymmetry, corresponding to a single Dirac spinor supercharge, the conditions are stronger.
19.
It can be seen as building upon the Kaluza Klein theory, which proposed a 4 + 1-dimensional theory of gravity.

Received notoriety when formulating the three-dimensional theory of law on which the right has three dimensions : social fact, legal norm.
