General frame

In logic, general frames (or simply frames) are Kripke frames with an additional structure, which are used to model modal and intermediate logics.

Jónsson cardinal

In set theory, a Jónsson cardinal (named after Bjarni Jónsson) is a certain kind of large cardinal number.

Jónsson function

In mathematical set theory, an ω-Jónsson function for a set x of ordinals is a function f:^\omega\to x with the property that, for any subset y of x with the same cardinality as x, the restriction of f to ^\omega is surjective on x. Here ^\omega denotes the set of strictly increasing sequences of members of x, or equivalently the family of subsets of x with order type \omega, using a standard notation for the family of subsets with a given order type.

Jónsson term

In universal algebra, within mathematics, a Jónsson term or majority term is a term t with exactly three free variables that satisfies the equations t(x, x, y).

Jónsson–Tarski algebra

In mathematics, a Jónsson–Tarski algebra or Cantor algebra is an algebraic structure encoding a bijection from an infinite set X onto the product X×X.

Logic

Logic (from the logikḗ), originally meaning "the word" or "what is spoken", but coming to mean "thought" or "reason", is a subject concerned with the most general laws of truth, and is now generally held to consist of the systematic study of the form of valid inference.

Model theory

In mathematics, model theory is the study of classes of mathematical structures (e.g. groups, fields, graphs, universes of set theory) from the perspective of mathematical logic.
