As a new topological phase in three-dimensional momentum space, Weyl semimetals extend the repertoire of exotic topological states. In this paper, we find the existence of photonic Weyl points in electromagnetic continuous gyromagnetic metamaterials. The

Some New Topologies on Ideal Topological Spaces
Proceedings of the National Academy of Sciences, India Section A: Physical Sciences, 2012In this paper we consider three types of space, and in these spaces, new types of generalized open set will be introduced. Further we shall introduce several types of topological space, and characterize the same.

Regularity in ideal grill topological space
Journal of Interdisciplinary Mathematics, 2023Among the basic concepts that have a vital role in producing comprehensive topologies is a regular space. In this respect, a new definition is introduced in the current study of separation properties. The term JG-regular is given to it. Then its important properties and connection with regular, JG-compact and H-closed are presented.

Subsets of ideal topological spaces
Acta Mathematica Hungarica, 2007An ideal topological space is a topological space \((X,\tau)\) with an ideal \(\mathcal I\) on \(X\). The ideal generates a new closure operator \(cl^*\) on \(X\). Using the operator \(cl^*\) several classes of sets in ideal spaces are defined and studied. These sets are generalizations of known generalized open and closed sets in topological spaces.

g-closed sets in ideal topological spaces
Acta Mathematica Hungarica, 2008Given a topological space \((X,\tau)\), an ideal \(\mathcal I\) in the powerset \(\mathcal P(X)\), and a subset \(A\subseteq X\), let \(A^*=\{x\in X:U\cap A\notin \mathcal I\;\text{for each open neighborhood }U ...

On subsets and decompositions of continuity in ideal topological spaces
2009We define new classes of sets called beta*-I-open set, pre*-I-open set, strongly t-I-set, beta*-t-I-set, strongly B-I-set, B*-I-set, strongly alpha-I-open set, and S-alpha-I-set in ideal topological spaces. Also, we obtain new decompositions of continuity in ideal topological spaces.
