Some sets of double lacunary invariant sequences defined by four dimensional summable matrices and Orlicz functions
Abstract
The paper introduces some sets of double lacunary invariant sequences defined by four dimensional RH-regular matrices and Orlicz functions. First we study some basic properties of such sets and equipped the sets with some relevant linear topological structures. Further, we investigate
for relationships among them under different conditions and finally compare with some sets of double statistically convergent sequences.
