Unbalanced spectral Turán problem for color-critical graphs with prescribed large maximum degree

Chang Liu

Let $F$ be a connected color-critical graph with $χ (F) = r + 1 \geq 4$ , let $S_{n, Δ}^{(r)} = (n - Δ) K_{1} \lor T (Δ, r - 1)$ . We determine the graph of maximum adjacency spectral radius among all $n…

Unbalanced Turán and spectral Turán problems with prescribed large maximum degree

Chang Liu

Classical Turán theory shows that, without additional constraints, the extremal structure of $F$ -free graphs is governed by the chromatic number of $F$ and is asymptotically the ba…
