Özet

In this paper, we study the concepts of Wijsman lacunary I-invariant convergence (I-sigma theta(W)), Wijsman lacunary I*-invariant convergence (I-sigma theta*(W)), Wijsman p-strongly lacunary invariant convergence ([WN sigma theta](p)) of sequences of sets and investigate the relationships among Wijsman lacunary invariant convergence, [WN sigma theta](p), I-sigma theta(W) and I-sigma theta*W. Also, we introduce the concepts of I-sigma theta -Cauchy sequence and I-sigma theta*W-Cauchy sequence of sets.
