We consider Hardy spaces with variable exponents defined by grand maximal function on the Heisenberg group. Then we introduce some equivalent characterizations
Let ? ∈ L~2(S~(n-1)) be homogeneous function of degree zero and b be BMO functions. In this paper, we obtain some boundedness of the Littlewood-Paley Operators
Let P(z) be a polynomial of degree n and for any complex number a, letDaP(z)=nP(z)+(a-z)P′(z) denote the polar derivative of the polynomial P(z) withrespect to a. In this p
