= Omega constant
{wiki=Omega_constant}
The Omega constant, denoted by the symbol \\( \\Omega \\), is a special number that is defined as the unique positive real solution to the equation \\\[ x = e^\{-x\}. \\\] This equation can also be written as: \\\[ x e^x = 1, \\\] which means that \\( \\Omega \\) is related to the Lambert W function, specifically the principal branch \\( W_0 \\).
