In mathematics, omega function refers to a function using the Greek letter omega, written ω or Ω. \Omega (big omega) may refer to: * The lower bound in Big O notation, f \in \Omega (g)\,\! , meaning that the function f\,\! dominates g\,\! in some limit * The prime omega function \Omega(n)\,\! , giving the total number of prime factors of n\,\! , counting them with their multiplicity. * The Lambert W function \Omega(x)\,\! , the inverse of y = x\cdot e^{x} \,\! , also denoted W(x)\,\! . * Absolute infinity \omega (omega) may refer to: * The Wright omega function \omega(x)\,\! , related to the Lambert W Function * The Pearson–Cunningham function \omega_{m,n}(x) * The prime omega function \omega(n)\,\! , giving the number of distinct prime factors of n\,\! .
