A novel technique for cohomology computations in engineering practice

► We present a novel algorithm for the computation of cohomology generators. ► The algorithm is based on a number of combinatorial and semi-algebraic algorithms. ► The core is a fast skeletonization algorithm for tetrahedral meshes. ► It yields a dramatic speed-up with respect to the best alternative method. ► It is useful in computational physics, computer-aided design, and computer graphics.
