plural of Arrhenius equation

(mathematics) An equation involving an ordered sequence of real numbers (a_nₙ₌₁ ᪲) and some of its differences, where the first difference is defined as 𝛥(a_n)=a_n+1-a_n, and the kᵗʰ difference is defined recursively as 𝛥ᵏ(a_n)=𝛥ᵏ⁻¹(a_n+1)-𝛥ᵏ⁻¹(a_n),.

(biology, genetics, cytology) The second of the two divisions of meiosis, a type of cell division.
