Their existence can be partly explained by the Brown-Shook model. A solution to the origin of one of them was provided by Jack Wisdom, who developed an algebraic mapping in 1983 permitting rapid integration. The Yarkovsky Effect can result in leakages through them, magnifying the possibility for orbit-crossing behavior. They arise from the same forces responsible for the Hilda and Thule groups, namely the mean-motion resonances ►with the orbital period of Jupiter. FTP, name these regions of the asteroid belt cleared of asteroids, certain "gaps"
