Galoitica: Journal of Mathematical Structures and Applications GJMSA 2834-5568 10.54216/GJSMA https://www.americaspg.com/journals/show/4294 2022 2022 Independent Researcher, Tokyo, Japan Takaaki Takaaki Associate Professor, Department of Mathematics, Tripura University, Agartala-799022, Tripura, India Ajoy Kanti Das A MetaStructure is a higher-level framework that treats entire collections of structures as single objects, equipped with natural operations that preserve isomorphisms across different domains. The term “Struc- ture” here refers broadly to mathematical systems as well as real-world models. An Iterated MetaStructure generalizes this idea recursively, generating successive layers in which structures of structures form deeper hierarchical meta-levels. In this work, we extend and investigate the properties of Algebra, Topology, Lattices, Queues, Markov Chains, and Intervals through the lens of MetaStructures and Iterated MetaStructures. 2026 2026 23 50 10.54216/GJMSA.130103 https://www.americaspg.com/articleinfo/33/show/4294
