The exact total degree threshold for the square of a Hamilton cycle in digraphs

Zhilan Wang, Shuo Wei, Jin Yan

The paper determines the exact minimum total degree condition that guarantees the square of a Hamilton cycle in large directed graphs, confirming the conjecture of DeBiasio et al.…

Ramsey-Turán Type Problem for Perfect Transitive Triangle Tilings in Digraphs

Zhimin Wang, Zhilan Wang, Jin Yan

The classical Corrádi-Hajnal theorem states that for any multiple of , if is a graph with vertices and , then can be partitioned into ver…

Oriented Discrepancy of The Square of Hamilton Cycles

Yufei Chang, Yangyang Cheng, Zhilan Wang +2

For an oriented graph , the oriented discrepancy problem concerns the existence of a spanning subgraph of with a large imbalance between its forward and backward edge orient…

The -linkage problems in sparse robustly expanding digraphs

Zhilan Wang, Jin Yan

The Nash-Williams conjecture establishes degree sequence conditions ensuring Hamilton cycles in digraphs. An asymptotic version of this conjecture for large digraphs was independen…

An Ore-type Theorem for Oriented Discrepancy of Hamilton Cycles

Yufei Chang, Yangyang Cheng, Zhilan Wang +2

Oriented graph discrepancy problems focus on finding specific subgraphs within a given oriented graph that contain a significant number of edges in one direction. This concept…

Spanning -subdivisions and perfect -subdivision tilings in dense digraphs

Yangyang Cheng, Zhilan Wang, Jin Yan

Given a (di)graph , we say that a (di)graph is an -subdivision if is obtained from by replacing one or more edges with internally vertex-disjoint pa…
