Minimal Entropy of $3$-manifolds
Abstract
We compute the Minimal Entropy of every closed, orientable -manifold, showing that its cube equals the sum of the cubes of the minimal entropies of each hyperbolic component arising from the decomposition of each prime summand. As a consequence we show that the cube of the Minimal Entropy is additive with respect to both the prime and the decomposition, thus concluding that for closed orientable -manifolds the cube of the Minimal Entropy is proportional to the simplicity volume. This answers a conjecture asked by Anderson and Paternain for irreducible manifolds.
