(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.

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

(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.

(political science) The theory that the far left and the far right, rather than being at opposite ends of a political continuum, in fact closely resemble one another.

(linguistics) A linguistic model proposing that the observed forms of language arise from the interaction between conflicting constraints.

A theory that explains the aggregation of aqueous dispersions quantitatively and describes the force between charged surfaces interacting through a liquid medium.

A branch of mathematics that studies the properties of topological spaces endowed with ℝᵏ-valued functions, with respect to the change of these functions.

(mathematics) A branch of functional analysis, being the study of linear operators on function spaces.

(quantum mechanics) The study of the analytic properties of scattering as a function of angular momentum, where the angular momentum is not restricted to an integer but may take any complex value.
