JEBRIL i.jebril@zuj.edu.jo Open Journal Systems <p>International Journal of Open Problems in Complex Analysis (IJOPCA) is a peer-reviewed journal, published two times a year that publishes articles which contribute new open problems in all areas of the Complex Analysis. All the papers in the IJOPCA are refereed papers by two international reviewers. We ask that you keep IJOPCA in mind when considering your next publication. All papers in IJOPCA are free reading and publishing articles and we ask that you keep IJOPCA in mind when considering your next publication. This journal is going to be valuable and helpful for all researchers in Complex analysis.</p> https://ijopca.icsrs.uk/index.php/IJOPCA/article/view/14 2026-01-30T12:23:01+00:00 Takaaki Fujita Takaaki.fujita060@gmail.com

<p>Graph theory offers a fundamental framework for representing and analyzing relationships among entities via vertices and edges. Hypergraphs extend this model by employing hyperedges that can connect multiple vertices simultaneously, enabling the capture of higher-order interactions.<br />Superhypergraphs generalize hypergraphs further by iteratively applying the powerset operation, thus supporting multi-level and selfreferential connection structures. In this paper, we introduce sphericalneutrosophic extensions based on spherical neutrosophic graphs by defining spherical neutrosophic hypergraphs and spherical neutrosophic superhypergraphs, and we investigate their fundamental properties. As an additional result, by incorporating ideas from complex spherical fuzzy sets, we define complex spherical neutrosophic superhypergraphs and examine their characteristics.</p>
