Effective genericity and differentiability. (English) Zbl 1345.03085

Summary: We prove that a real \(x\) is 1-generic if and only if every differentiable computable function has continuous derivative at \(x\). This provides a counterpart to recent results connecting effective notions of randomness with differentiability. We also consider multiply differentiable computable functions and polynomial time computable functions.
