Finite palette endpoints and degree-square Turán problems
Jiangdong Ai, Bin Chen, Ming Chen +2
The paper investigates extremal color‑palette problems motivated by uniform Turán densities of 3‑uniform hypergraphs, showing they reduce to maximizing the sum of squared out‑degre…

A weighted cycle-localization inequality
Jiangdong Ai, Bin Chen, Ming Chen +1
In 1959, ErdÅs and Gallai showed that every -connected graph contains a cycle of length at least . This result was subsequently extended to weight…

Strongly regular graphs with parameters (85,14,3,2) do not exist
Sergey Shpectorov, Tianxiao Zhao
We investigate the second smallest unresolved feasible set of parameters of strongly regular graphs, . Using the classification of cubic graphs of small de…
