Contour Hankel dynamics and indicator fields for the Riemann -function
Zhiliang Deng, Xiaomei Yang, Huazhong Lü
We develop a moving-contour Hankel framework for encoding local zero configurations of the Riemann -function. Weighted contour integrals of the logarithmic derivative , ex…
On complexity of substructure connectivity and restricted connectivity of graphs
Huazhong Lü, Tingzeng Wu
The connectivity of a graph is an important parameter to evaluate its reliability. -restricted connectivity (resp. -restricted connectivity) of a graph is the minimum c…
Paired many-to-many 2-disjoint path cover of Johnson graphs
Jinhao Liu, Huazhong Lü
Given two 2 disjoint vertex-sets and , a paired many-to-many 2-disjoint path cover joining S and T, is a set of two vertex-disjoint paths with endpoints $u,v…
Brualdi-Goldwasser-Michael problem for maximum permanents of {\rm(0,1)}-matrices
Tingzeng Wu, Xiangshuai Dong, Huazhong Lü
Let be the set of all {\rm(0,1)}-matrices of order with exactly 0's. Brualdi et al. investigated the maximum permanents of all matrices in $\mathscr{U}…
Symmetric properties and two variants of shuffle-cubes
Huazhong Lü, Kai Deng, Xiaomei Yang
Li et al. in [Inf. Process. Lett. 77 (2001) 35--41] proposed the shuffle cube as an attractive interconnection network topology for massive parallel and distributed system…
