Esi, Ayhan Double lacunary sequence spaces of double sequence of interval numbers. (English) Zbl 1263.46005 Proyecciones 31, No. 3, 297-306 (2012). Summary: We introduce the concepts of double lacunary strong convergence and double lacunary statistical convergence of double interval numbers. We prove some inclusion relations and study some of their properties.
