Group field theory (GFT) is a quantum field theory in which the base manifold is taken to be a Lie group. It is closely related to background independent quantum gravity approaches such as loop quantum gravity, the spin foam formalism and causal dynamical triangulation. It can be shown that its perturbative expansion can be interpreted as spin foams and simplicial pseudo-manifolds (depending … WebThese axioms are identical to those of a field, except that we impose fewer requirements on the ordered pair $(R\setminus\{0\},\times)$: it now only has to be an associative …
WebSep 12, 2024 · Group theory is the branch of mathematics that includes the study of elements in a group. Group is the fundamental concept of algebraic structure like other algebraic structures like rings and fields. Group: A non-empty set G with * as operation, (G, *) is called a group if it follows the closure, associativity, identity, and inverse properties. WebMay 7, 2024 · Field theory was developed by Kurt Lewin in 1951. The theory has gained a lot of significance over the years and its applicability has increased significantly in various domains such as physical and social sciences. According to Martin (2003), field theory tries to explain how change occurs in various amongst individuals and organizations.
