A well understood and illustrative example of an instanton and its interpretation can be found in the context of a QFT with a non-abelian gauge group, [note 2] a Yang–Mills theory. For a Yang–Mills theory these inequivalent sectors can be (in an appropriate gauge) classified by the third homotopy group of SU(2) (whose group manifold is the ...
Newell and Simon carried out psychological experiments that showed that, for difficult problems in logic, planning, or any kind of "puzzle solving", people carefully proceeded step-by-step, considering several different possible ways forward, selected the most promising one, backing up when the possibility hit a dead end. Each possible solution ...
Quantum Yang–Mills theory with a non-abelian gauge group and no quarks is an exception, because asymptotic freedom characterizes this theory, meaning that it has a trivial UV fixed point. Hence it is the simplest nontrivial constructive QFT in 4 dimensions. (QCD is a more complicated theory because it involves quarks.)
In mathematics, the Simon problems (or Simon's problems) are a series of fifteen questions posed in the year 2000 by Barry Simon, an American mathematical physicist. [ 1 ] [ 2 ] Inspired by other collections of mathematical problems and open conjectures, such as the famous list by David Hilbert , the Simon problems concern quantum operators . [ 3 ]
Administrative Behavior: a Study of Decision-Making Processes in Administrative Organization is a book written by Herbert A. Simon (1916–2001). It asserts that "decision-making is the heart of administration, and that the vocabulary of administrative theory must be derived from the logic and psychology of human choice", and it attempts to describe administrative organizations "in a way that ...
Simon's problem considers access to a function : {,} {,}, as implemented by a black box or an oracle. This function is promised to be either a one-to-one function, or a two-to-one function; if is two-to-one, it is furthermore promised that two inputs and ′ evaluate to the same value if and only if and ′ differ in a fixed set of bits. I.e.,
Through the process of dimensional reduction, the Yang–Mills equations may be used to derive other important equations in differential geometry and gauge theory. Dimensional reduction is the process of taking the Yang–Mills equations over a four-manifold, typically R 4 {\displaystyle \mathbb {R} ^{4}} , and imposing that the solutions be ...
The work on the behavioral theory started in 1952 when March, a political scientist, joined Carnegie Mellon University, where Cyert was an economist. [2] Before this model was formed, the existing theory of the firm had two main assumptions: profit maximization and perfect knowledge. Cyert and March questioned these two critical assumptions.
