Binary operations | Algebraic properties of elements | Semigroup theory

In mathematics, an absorbing element (or annihilating element) is a special type of element of a set with respect to a binary operation on that set. The result of combining an absorbing element with any element of the set is the absorbing element itself. In semigroup theory, the absorbing element is called a zero element because there is no risk of confusion with other notions of zero, with the notable exception: under additive notation zero may, quite naturally, denote the neutral element of a monoid. In this article "zero element" and "absorbing element" are synonymous. (Wikipedia).

Thermal conductivity is the constant of proportionality for heat transfer in response to a temperature gradient. Thermal conductivity can be accomplished by contributions from electrons, phonons, radiation, and convection. Metals have high thermal conduction due to the many free electrons,
