Self-Duality and New TQFTs for Forms [PDF]
, 1998 We discuss theories containing higher-order forms in various dimensions. We explain how Chern--Simons-type theories of forms can be defined from TQFTs in one less dimension.

Modular Matrices as Topological Order Parameter by Gauge Symmetry Preserved Tensor Renormalization Approach [PDF]
, 2014 Topological order has been proposed to go beyond Landau symmetry breaking theory for more than twenty years. But it is still a challenging problem to generally detect it in a generic many-body state.

On Degree-Based Topological Indices of Symmetric Chemical Structures [PDF]
Symmetry, 2018 A Topological index also known as connectivity index is a type of a molecular descriptor that is calculated based on the molecular graph of a chemical compound. Topological indices are numerical parameters of a graph which characterize its topology and are usually graph invariant.

On Degree-Based Topological Indices of Petersen Subdivision Graph
European Journal of Mathematical Analysis, 2023 In this paper, we adequately describe the generalised petersen graph, expanding to the categories of graphs. We created a petersen graph, which is cyclic and has vertices that are arranged in the centre and nine gons plus one vertex, leading to the ...

Computation of Topological Indices of Some Special Graphs
Mathematics, 2018 There are several chemical indices that have been introduced in theoretical chemistry to measure the properties of molecular topology, such as distance-based topological indices, degree-based topological indices and counting-related topological indices ...

Degree-Based Entropy for a Non-Kekulean Benzenoid Graph
Journal of Mathematics, 2022 Tessellations of kekulenes and cycloarenes have a lot of potential as nanomolecular belts for trapping and transporting heavy metal ions and chloride ions because they have the best electronic properties and pore sizes. The aromaticity, superaromaticity,

Topological Study of Zeolite Socony Mobil-5 via Degree-Based Topological Indices
Journal of Chemistry, 2021 Graph theory is a subdivision of discrete mathematics. In graph theory, a graph is made up of vertices connected through edges. Topological indices are numerical parameters or descriptors of graph.

Degree-Based Topological Indices and QSPR Analysis of Antituberculosis Drugs
Journal of chemistry, 2022 A topological index of graph G is a numerical quantity which describes its topology. If it is applied to molecular structure of a chemical compounds, then it reflects the theoretical properties of the chemical compounds.

On Degree-Based Topological Indices for Strong Double Graphs
Journal of Chemistry, 2021 A topological index is a characteristic value which represents some structural properties of a chemical graph. We study strong double graphs and their generalization to compute Zagreb indices and Zagreb coindices.
