field theoryIn mathematics, the study of the structure of a set of objects (e.g., numbers) with two combining operations (e.g., addition and multiplication). Such a system, known as a field, must satisfy certain properties: associative law, commutative law, distributive law, an additive identity (“zero”), a muliplicative identity (“one”), additive inverses (see inverse function), and multiplicative inverses for nonzero elements. The sets of rational numbers, real numbers, and complex numbers are fields under ordinary addition and multiplication. The investigation of polynomial equations and their solutions led to the development of field theory. |

Word is that the elusive unified field theory remains elusive. He and others later constructed the quantum field theory of quarks and gluons called quantum chromodynamics, which seems to account for all the nuclear particles and their strong interactions. New results based on the applications of effective field theory for neutron decay is presented. |
