TY - JOUR TI - Strongly Summable Vector-Valued Sequence Spaces Defined by 2-modular AU - Nurnugroho, Burhanudin Arif; Prasetyo, Puguh Wahyu IS - Vol 6, No 4 (2021): CAUCHY: Jurnal Matematika Murni dan Aplikasi PB - Mathematics Department, Maulana Malik Ibrahim State Islamic University of Malang JO - CAUCHY PY - 2021 SP - 279 EP - 285 UR - http://ejournal.uin-malang.ac.id/index.php/Math/article/view/11484/pdf AB - Summability is an important concept in sequence spaces. One summability concept is strongly Cesaro summable. In this paper, we study a subset of the set of all vector-valued sequence in 2-modular space. Some facts that we investigated in this paper include linearity, the existence of modular and completeness with respect to these modular.
