Hyperbolic manifolds with a large number of systoles (2210.00154v2)

Abstract: In this article, for any $n\geq 4$ we construct a sequence of compact hyperbolic $n$-manifolds ${M_i}$ with number of systoles at least as $\mathrm{vol}(M_i)^{1+\frac{1}{3n(n+1)}-\epsilon}$ for any $\epsilon>0$. In dimension 3, the bound is improved to $\mathrm{vol}(M_i)^{\frac{4}{3}-\epsilon}$. These results generalize previous work of Schmutz for $n=2$, and D\'oria-Murillo for $n=3$ to higher dimensions.
