Topological spaces form the foundational framework for modern analysis and geometry, characterised by a set equipped with a collection of open subsets satisfying specific axioms. This flexible ...

The Menger property, a renowned covering property in topology, offers a generalisation of σ‑compactness by asserting that for any sequence of open covers, one can select finitely many elements from ...

Abstract.In this paper, we study the concept of soft sets which is introduced by Molodtsov [5] and the notion of soft continuity is introduced by Zorlutuna et al. [8]. We give the definition of (𝜏₁, ...

The topological photonics plays an important role in the fields of fundamental physics and photonic devices. The Kagome model, the Su-Schrieffer-Heeger (SSH) model and the other topological models are ...

At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The ...
