In this paper, we study the concepts of Wijsman lacunary \({\mathcal{I}}\)-invariant convergence \(\left( {{\mathcal{I}}_{\sigma \theta }^{W} } \right),\) Wijsman lacunary \({\mathcal{I}}^{ *}\)-invariant convergence \(\left( {{\mathcal{I}}_{\sigma \theta }^{ *W} } \right),\) Wijsman \(p\)-strongly lacunary invariant convergence \(\left( {[WN_{\sigma \theta } ]_{p} } \right)\) of sequences of sets and investigate the relationships among Wijsman lacunary invariant convergence, \([WN_{\sigma \theta } ]_{p}\), \({\mathcal{I}}_{\sigma \theta }^{W}\) and \({\mathcal{I}}_{\sigma \theta }^{ *W}\). Also, we introduce the concepts of \({\mathcal{I}}_{\sigma \theta }^{W}\)-Cauchy sequence and \({\mathcal{I}}_{\sigma \theta }^{ *W}\)-Cauchy sequence of sets.

Wijsman Lacunary $$ {\ mathbf {\ mathcal {I}}} $$ I-集序列的不变收敛
在本文中,我们研究了Wijsman词法\({\ mathcal {I}} \)-不变收敛\(\ left({{\ mathcal {I}} _ {\ sigma \ theta} ^ {W}}的概念\ right),\) Wijsman腔(\ {{\ mathcal {I}} ^ {*} \)-不变收敛\(\ left({{\ mathcal {I}} _ {\ sigma \ theta} ^ {* W }} \右),\) Wijsman \(p \) -strongly缺位不变收敛\(\左({[WN _ {\西格玛\ THETA}] _ {p}} \右)\)的序列集,并调查Wijsman恒常不变收敛,\([WN _ {\ sigma \ theta}] _ {p} \),\({\ mathcal {I}} _ {\ sigma \ theta} ^ {W} \)和\之间的关系({\ mathcal {I}} _ {\ sigma \ theta} ^ {* W} \)。此外,我们介绍了\({\ mathcal {I}} _ {\ sigma \ theta} ^ {W} \)-漂亮序列和\({\ mathcal {I}} _ {\ sigma \ theta} ^的概念{* W} \) -集的模糊序列。
