Abstract:

Weak Musielak-Orlicz-Triebel-Lizorkin spaces with variable smooth exponent are first introduced. Then we establish a vector estimate for weak Musielak-Orlicz spaces. As an application we give equivalent quasi-norms in these new spaces by means of Peetre 's maximal functions. Finally, we obtain the boundedness of the φ transform on these new spaces and their atomic and molecular decompositions.

Key words: variable smooth exponent, weak Musielak-Orlicz space, triebel-Lizorkin space, atom, molecule, maximal function
