On the enumeration of uniquely reducible double designs [PDF]

Discrete Mathematics & Theoretical Computer Science, 2005
A double $2$-$(v,k,2 \lambda)$ design is a design which is reducible into two $2$-$(v,k,\lambda)$ designs. It is called uniquely reducible if it has, up to equivalence, only one reduction.

Odd Harmonious Labeling of P_n ⊵ C₄ and  P_n ⊵ D₂(C₄)

Indonesian Journal of Combinatorics, 2021
A graph G with q edges is said to be odd harmonious if there exists an injection f:V(G) → ℤ2q so that the induced function f*:E(G)→ {1,3,...,2q-1} defined by f*(uv)=f(u)+f(v) is a bijection.Here we show that graphs constructed by edge comb product of ...

Graph WaveNet for Deep Spatial-Temporal Graph Modeling [PDF]

International Joint Conference on Artificial Intelligence, 2019
Spatial-temporal graph modeling is an important task to analyze the spatial relations and temporal trends of components in a system. Existing approaches mostly capture the spatial dependency on a fixed graph structure, assuming that the underlying ...
