For every holomorphic function in two complex variables with an isolated critical point at the origin we consider the Łojasiewicz exponent 𝓛₀(f) defined to be the smallest θ > 0 such that $|grad f(z)| ≥ c|z|^{θ}$ near 0 ∈ ℂ² for some c > 0. We investigate the set of all numbers 𝓛₀(f) where f runs over all holomorphic functions with an isolated critical point at 0 ∈ ℂ².
