Abstract

We prove that every immersed \(C^2\)-curve \(\gamma \) in \(\mathbb R^n\), \(n\geqslant 3\) with curvature \(k_{\gamma }\) can be \(C^1\)-approximated by immersed \(C^2\)-curves having prescribed curvature \(k>k_{\gamma }\). The approximating curves satisfy a \(C^1\)-dense h-principle. As an application we obtain the existence of \(C^2\)-knots of arbitrary positive curvature in each isotopy class, which generalizes a similar result by McAtee for \(C^2\)-knots of constant curvature.
