The structure of topological spaces is analysed here through the lenses fibrous preorders. Each space has an associated preorder and those preorders which return a are called spatial. A special class spatial consisting interconnected family indexed by unitary magma Cartesian studied here. Topological that obtained from preorders, with I, I-Cartesian characterized. characterization reveals hidde...

We show that Floquet chiral topological superconductivity arises naturally in Josephson junctions made of magnetic insulator-superconductor sandwich structures. The phase modulation associated with an applied bias voltage across the junction drives system into anomalous superconductor hosting Majorana edge modes quasienergy spectrum, bulk bands carrying zero Chern numbers. acts as a tuning para...

A topological RNA structure is derived by fattening the edges of a contact structure into ribbons. The shape of a topological RNA structure is obtained by collapsing the stacks of the structure into single arcs and by removing any arcs of length one, as well as isolated vertices. A shape contains the key topological information of the molecular conformation and for fixed topological genus there...

This work introduces a novel topological constraint called the intopological digraph space imposed by subbasis ... contains one vertice such that edge ẹ is indegree of it and investigates some properties this structure. Our objective to provide crucial first step in study characteristics digraphs utilizing appropriate topology.
