The theta-criterion (also named θ-criterion) is a constraint on x-bar theory that was first proposed by Noam Chomsky as a rule within the system of principles of the government and binding theory, called theta-theory (θ-theory). As theta-theory is concerned with the distribution and assignment of theta-roles (a.k.a. thematic roles), the theta ...
Negatively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules decreases. n = 1 {\displaystyle n=1} . Noncooperative (completely independent) binding : The affinity of the enzyme for a ligand molecule is not dependent on whether or not other ligand molecules are already bound.
In government and binding theory this is known as proper government. Proper government occurs either if the empty position is governed by a lexical category (especially if it is not a subject) (theta-government) or if it is coindexed with a maximal projection which governs it (antecedent-government). The ECP has been revised many times and is ...
In the mathematical fields of set theory and proof theory, the Takeuti–Feferman–Buchholz ordinal (TFBO) is a large countable ordinal, which acts as the limit of the range of Buchholz's psi function and Feferman's theta function. [1] [2] It was named by David Madore, [2] after Gaisi Takeuti, Solomon Feferman and Wilfried Buchholz.

In mathematics, the theta correspondence or Howe correspondence is a mathematical relation between representations of two groups of a reductive dual pair. The local theta correspondence relates irreducible admissible representations over a local field , while the global theta correspondence relates irreducible automorphic representations over a ...
The following approaches can all be seen as exemplifying a generalization of Darwinian ideas outside of their original domain of biology. These "Darwinian extensions" can be grouped in two categories, depending on whether they discuss implications of biological (genetic) evolution in other disciplines (e.g. medicine or psychology), or discuss processes of variation and selection of entities ...
