Efficient $(3,3)$-isogenies on fast Kummer surfaces
Abstract
We give an alternative derivation of $(N,N)$-isogenies between fast Kummer surfaces which complements existing works based on the theory of
theta functions. We use this framework to produce explicit formulae for the case of $N = 3$, and show that the resulting algorithms are more efficient than all prior $(3, 3)$-isogeny algorithms.
