摘要：
The interior regularity of solutions to an obstacle problem relative to a quasilinear degenerate elliptic operator is discussed. In the usual framework of classical elliptic operators this is a well-known problem, extensively studied. In the study the first-order derivatives are substituted with Hormander vector fields and then the regularity results are extended due to this new setting.
