When is an ordinal greater than 1 an indecomposable number?
A δ-number (see Multiplicatively indecomposable) is an ordinal greater than 1 such that αβ = β whenever 0< α < β. These consist of the ordinal 2 and the ordinals of the form ω ωβ . The definition of ordinal exponentiation for finite exponents is straightforward. If the exponent is a finite number, the power is the result of iterated multiplication.
