Glaisher
is Glaisher's constant with numerical value .
Background & Context
- Glaisher is the symbol representing Glaisher's constant
, also known as the Glaisher–Kinkelin constant. Glaisher has a number of equivalent definitions throughout mathematics but is most commonly defined as the constant
that satisfies
, where
is the Riemann zeta function Zeta,
is its derivative evaluated at
, and Log is the natural logarithm. Glaisher has a numerical value
. Glaisher arises in mathematical computations including sums, products, and integrals but is especially prominent in sums and integrals involving Gamma and Zeta functions.
- When Glaisher is used as a symbol, it is propagated as an exact quantity. Expansion and simplification of complicated expressions involving Glaisher may require use of functions such as FunctionExpand and FullSimplify.
- It is not currently known if Glaisher is rational (meaning it can be expressed as a ratio of integers), algebraic (meaning it is the root of some integer polynomial), or normal (meaning the digits in its base-
expansion are equally distributed) to any base.
- Glaisher can be evaluated to arbitrary numerical precision using N. However, no efficient formulas for computing large numbers of its digits are currently known. RealDigits can be used to return a list of digits of Glaisher and ContinuedFraction to obtain terms of its continued fraction expansion.
