Cookie cutters: Bisections with fixed shapes
Advances in Applied MathematicsIn a mass partition problem, we are interested in finding equitable partitions of smooth measures in $\mathbb{R}^d$. In this manuscript, we study the problem of finding simultaneous bisections of measures using scaled copies of a prescribed set $K$.
