Abstract
In this paper, we introduce and investigate Sobolev regularity properties of the local bilinear maximal operator and its fractional variant. Some new bounds for the derivatives of the above maximal functions are established. These estimates can be used to obtain boundedness and continuity for these operators in Sobolev spaces as well as the bounds of these operators on the Sobolev spaces with zero boundary values.
