(physics) The theory that (most) baryons and mesons are composed of bound quarks and antiquarks.

(physics) A mathematical approach to developing a theory of everything in theoretical physics, based on quantizing spacetime into units called metrons.

A mathematical technique for finding an approximate solution to a problem that cannot be solved exactly, by starting from the exact solution of a related problem; used in modelling physical interactions between particles, etc.

(uncountable, algebra, algebraic geometry, algebraic topology) The study of rings R generated by the set of vector bundles over some topological space or scheme;

(mathematics, uncountable) The study of the properties of dynamic systems over large timescales.

(topology) The branch of topology devoted to the study of continua, a type of metric space.

(mathematics) One aspect of the study of differential forms of a smooth manifold M. More specifically, it works out the consequences for the cohomology groups of M, with real coefficients, of the partial differential equation theory of generalised Laplacian operators associated to a Riemannian metric on M.

(psychology) The ability to form an opinion about what other people are thinking.

(mathematics) Those theories extending the eigenvalue and eigenvector theory of a single square matrix to a much broader theory of the structure of operators in a variety of mathematical spaces.

A mathematical formalism developed in the 1980s for the representation of meaning or semantics.
