Abstract
This paper is devoted to studying the regularity properties for the new maximal operator Mφ{M_{\varphi}} and the fractional new maximal operator Mφ,β{M_{\varphi,\beta}} in the local case. Some new pointwise gradient estimates of Mφ,Ω{M_{\varphi,\Omega}} and Mφ,β,Ω{M_{\varphi,\beta,\Omega}} are given. Moreover, the boundedness of Mφ,Ω{M_{\varphi,\Omega}} and Mφ,β,Ω{M_{\varphi,\beta,\Omega}} on Sobolev space is established. As applications, we also obtain the bounds of the above operators on Sobolev space with zero boundary values.
