Object Filippov theory of differential equations with discontinuous right-hand sides
Filippov theory of differential equations with discontinuous right-hand sides is a mathematical framework that generalizes classical differential equation theory to rigorously define and analyze solutions of systems whose dynamics are governed by discontinuous vector fields, such as in control and mechanical systems with switching or impacts.
