The twisted index and topological saddles
Journal of High Energy Physics, 2022 The twisted index of 3d N $$ \mathcal{N} $$ = 2 gauge theories on S 1 × Σ has an algebro-geometric interpretation as the Witten index of an effective supersymmetric quantum mechanics.

Topological gravity for arbitrary Dyson index
Journal of High Energy PhysicsWe use the well established duality of topological gravity to a double scaled matrix model with the Airy spectral curve to define what we refer to as topological gravity with arbitrary Dyson index β (β topological gravity).

Novel Degree-Based Topological Descriptors of Fenofibrate Using M-Polynomial
Journal of Mathematics, 2023 Chemical graph theory is currently expanding the use of topological indices to numerically encode chemical structure. The prediction of the characteristics provided by the chemical structure of the molecule is a key feature of these topological indices ...

Computation of Revan Topological Indices for Phenol-Formaldehyde Resin
Journal of Mathematics, 2022 Phenol-formaldehyde resin has a wide range of moldings. The phenolic resin retains properties at the freezing point; hence, it is difficult to determine its age.
