TY - JOUR T1 - Sharp $B$-Maximal Function Estimates and Boundedness for Some Integral Operators to the Inequalities AU - Keskin, Cansu AU - Turkak, Havva Nur PY - 2025 DA - June Y2 - 2025 DO - 10.53570/jnt.1696750 JF - Journal of New Theory JO - JNT PB - Naim ÇAĞMAN WT - DergiPark SN - 2149-1402 SP - 65 EP - 75 IS - 51 LA - en AB - In this paper, we first establish the relation between $B$-maximal and sharp $B$-maximal functions generated by the generalized translation operator connected with the Laplace-Bessel differential operator. We then prove some sharp $B$-maximal function estimates and present an application using these sharp estimates to study singular integral operators. We finally obtain the boundedness of the Littlewood-Paley $g$-function related to the Laplace-Bessel differential operator on generalized $B$-Morrey spaces.
