Abstract
The integrability of billiards bounded by arcs of confocal quadrics in the Minkowski plane in a field with the Hooke potential is obtained. The case of this type of a billiard in an ellipse is studied in detail. In addition to that, the topology of Liouville foliations arising in this problem is studied and Fomenko invariants are constructed.
