2. Exponentiation - Wikipedia

   en.wikipedia.org/wiki/Exponentiation

   Exponentiation with negative exponents is defined by the following identity, which holds for any integer n and nonzero b: =. [1] Raising 0 to a negative exponent is undefined but, in some circumstances, it may be interpreted as infinity (). [22]

3. Power associativity - Wikipedia

   en.wikipedia.org/wiki/Power_associativity

   Over a field of characteristic 0, an algebra is power-associative if and only if it satisfies [,,] = and [,,] =, where [,,]:= () is the associator (Albert 1948). Over an infinite field of prime characteristic p > 0 {\displaystyle p>0} there is no finite set of identities that characterizes power-associativity, but there are infinite independent ...

4. Exponential function - Wikipedia

   en.wikipedia.org/wiki/Exponential_function

   Exponential functions with bases 2 and 1/2. In mathematics, the exponential function is the unique real function which maps zero to one and has a derivative equal to its value. . The exponential of a variable ⁠ ⁠ is denoted ⁠ ⁡ ⁠ or ⁠ ⁠, with the two notations used interchangeab

5. Lifting-the-exponent lemma - Wikipedia

   en.wikipedia.org/wiki/Lifting-the-exponent_lemma

   In elementary number theory, the lifting-the-exponent lemma (LTE lemma) provides several formulas for computing the p-adic valuation of special forms of integers. The lemma is named as such because it describes the steps necessary to "lift" the exponent of p {\displaystyle p} in such expressions.

6. Matrix exponential - Wikipedia

   en.wikipedia.org/wiki/Matrix_exponential

   The matrix exponential satisfies the following properties. [2] We begin with the properties that are immediate consequences of the definition as a power series: e 0 = I; exp(X T) = (exp X) T, where X T denotes the transpose of X. exp(X ∗) = (exp X) ∗, where X ∗ denotes the conjugate transpose of X. If Y is invertible then e YXY −1 = Ye ...

7. Tetration - Wikipedia

   en.wikipedia.org/wiki/Tetration

   There is no standard notation for tetration, though Knuth's up arrow notation and the left-exponent x b are common. Under the definition as repeated exponentiation, n a {\displaystyle {^{n}a}} means a a ⋅ ⋅ a {\displaystyle {a^{a^{\cdot ^{\cdot ^{a}}}}}} , where n copies of a are iterated via exponentiation, right-to-left, i.e. the ...
