TY - JOUR T1 - Lifts of $L$-valued powerset mapping systems AU - Zhou, Chang-jie AU - Yao, Wei PY - 2025 DA - October Y2 - 2024 DO - 10.15672/hujms.1553887 JF - Hacettepe Journal of Mathematics and Statistics PB - Hacettepe University WT - DergiPark SN - 2651-477X SP - 1730 EP - 1736 VL - 54 IS - 5 LA - en AB - Motivated by Zadeh's extension of mappings, this paper introduces a concept of lifts of powerset mapping systems. In this framework, $L$-subsets are lifts of ordinary subsets, $L$-Zadeh functions are lifts of ordinary mappings, $L$-fuzzy rough set operators are lifts of classical rough set operators, $L$-interior/closure operators of $L$-topology are lifts of interior/closure operators of level topologies. Consequently, lifts of powerset mapping systems can be considered as a useful fuzzy structures for future study.
