The omega constant is a mathematical constant defined as the unique real number that satisfies the equation = It is the value of W(1), where W is Lambert's W function. The name is derived from the alternate name for Lambert's W function, the omega function. The numerical value of Ω is given by

In mathematical logic, an ω-consistent (or omega-consistent, also called numerically segregative) [1] theory is a theory (collection of sentences) that is not only (syntactically) consistent [2] (that is, does not prove a contradiction), but also avoids proving certain infinite combinations of sentences that are intuitively contradictory.
the time constant of any device, such as an RC circuit; proper time in relativity; one turn: the constant ratio of a circle's circumference to its radius, with value (6.283...).

In 2010, Hartl published The Tau Manifesto, in which he proposed using the Greek letter tau to represent the circle constant τ = C/r = 2π, [35] the first time tau was publicly proposed for this purpose. [1] [6] The Tau Manifesto proved popular, [36] and a revised edition was published in 2019, [37] followed by a print edition in 2021.
If f and g are functions from the metric space X to the Banach space Y, with moduli respectively ω 1 and ω 2, then any linear combination af+bg has modulus of continuity |a|ω 1 +|b|ω 2. In particular, the set of all functions from X to Y that have ω as a modulus of continuity is a convex subset of the vector space C ( X , Y ), closed under ...

In physics and engineering, the time constant, usually denoted by the Greek letter τ (tau), is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system. [1] [note 1] The time constant is the main characteristic unit of a first-order LTI system. It gives speed of the response.
