Triple bar

The triple bar, or tribar ≡, is a symbol with multiple, context-dependent meanings. It has the appearance of an equals sign ⟨=⟩ sign with a third line. The triple bar character in Unicode is code point U+2261 ≡ IDENTICAL TO (≡, ≡). The closely related code point U+2262 ≢ NOT IDENTICAL TO (≢, ≢) is the same symbol with a slash through it, indicating the negation of its mathematical meaning. In LaTeX mathematical formulas, the code \equiv produces the triple bar symbol and ot\equiv produces the negated triple bar symbol as output. (Wikipedia).

Walter van Suijlekom: Semigroup of inner perturbations in Non Commutative Geometry

Starting with an algebra, we define a semigroup which extends the group of invertible elements in that algebra. As we will explain, this semigroup describes inner perturbations of noncommutative manifolds, and has applications to gauge theories in physics. We will present some elementary e
