On Topological Indices And Domination Numbers Of Graphs
Topological indices and dominating problems are popular topics in Graph Theory. There are various topological indices such as degree-based topological indices, distance-based topological indices and counting related topological indices et al. These topological indices correlate certain …

2d quantitative structure activity relationship modeling of methylphenidate analogues using algorithm and partial least square regression
… descriptors. 2D QSAR uses descriptors, such as topological indices, that are independent of molecular conformation. A genetic algorithm - partial least squares (GA-PLS) approach was used to identify the molecular descriptors that correlate to the biological activity (binding affinity) of a set …

Topics on critical point theory
… In order to do this, we isolate various topological indices that can be associated with certain critical sets and points. If the functionals are C2 and the critical points are non-degenerated, these indices can then be used to recover the standard results on Morse indices. The study in …

Higher-order topological phases with crystalline symmetries
Topological insulators (TIs) that are insulating in the bulk but conducting at surfaces have been thoroughly studied for decades. Recently, a new class of TIs, dubbed the higher-order topological insulator (HOTI), has been discovered. Unlike conventional TIs, it is gapped at the boundaries but host …

Structure vs. Properties Using Chemical Graph Theory
… of such systems with extremal Wiener indices. We provide a labeling of the vertices on each hexagon, which facilitates the illustration of a tree-like polyphenyl system with its corresponding tree structure. This approach helps to characterize the extremal tree-like polyphenyl systems …
