 # Efficient space-time adaptivity for parabolic evolution equations using wavelets in time and finite elements in space
-This repository contains an implementation of arXiv:2101.03956, as described in.
+This repository contains the implementation that was used to generate the numerics in arXiv:2104.08143 and arXiv:2101.03956.
 
 This project provides a linear complexity implementation of a space-time
-adaptive solver for parabolic evolution equations.  The trial spaces that
-we consider here are given as sparse tensor product approximations
-of wavelets-in-time and (locally refined) finite element spaces-in-space.
-Special care has to be taken to evaluate matrix-vector products, as the
-system-matrix w.r.t. such a multi-level type basis is not sparse. By restricting
-to bases that are spanned by tensor products having index sets that form double-trees,
-we can still evaluate the system matrices in linear complexity.

-Aiming at a truly linear-complexity implementation, we implemented this algorithm
-using tree-based algorithms, without the use of hash maps.
