f(n)=O(T(n))f(n)=O(T(n)) if there exists a positive real number M and a real number n0 such that

f(n)MT(n)f(n)\le MT(n) for all nn0n\ge n_0


f(n)=Ω(T(n))f(n)=\Omega(T(n)) if there exists a positive real number M and a real number n0 such that

f(n)MT(n)f(n)\ge MT(n) for all nn0n\ge n_0


f(n)=θ(T(n))f(n)=\theta(T(n)) if there exists a positive real numbers M1, M2 and a real number n0 such that

M1T(n)f(n)M2T(n)M_1T(n)\le f(n)\le M_2T(n) for all nn0n\ge n_0
