Triangle decompositions of $\lambda K_v-\lambda K_w-\lambda K_u$

Yueting Li, Yanxun Chang, Tao Feng

Denote by $\lambda K_v$ the complete graph of order $v$ with multiplicity $\lambda$. Let $\lambda K_v-\lambda K_w-\lambda K_u$ be the graph obtained from $\lambda K_v$ by the removal of the edges of two vertex disjoint co…
