An eclipse's rating on the Danjon Scale is traditionally denoted by the letter L.

This is traditionally denoted a "writeable control store" in the context of computers.

The Hamiltonian represents the total energy of the system, which is the sum of kinetic and potential energy, traditionally denoted T and V, respectively.

In mathematics, the first uncountable ordinal, traditionally denoted by ω or sometimes by Ω, is the smallest ordinal number that, considered as a set, is uncountable.

In its simplest form, an ARS is simply a set (of "objects") together with a binary relation, traditionally denoted with ; this definition can be further refined if we index (label) subsets of the binary relation.

The following quantity is a constant which is traditionally denoted by β, known as the thermodynamic beta.

An ARS is simply a set A, whose elements are usually called objects, together with a binary relation on A, traditionally denoted by , and called the reduction relation, rewrite relation or just reduction.

The abstract vectors of quantum theory correspond to the wavefunction (traditionally denoted by w) of Schrödinger's wave mechanics.

If an index transforms like a vector with the inverse of the basis transformation, it is called contravariant and is traditionally denoted with an upper index, while an index that transforms with the basis transformation itself is called covariant and is denoted with a lower index.

In statistics, binomial regression is a technique in which the response (often referred to as Y) is the result of a series of Bernoulli trials, or a series of one of two possible disjoint outcomes (traditionally denoted "success" or 1, and "failure" or 0).
