Lu, You; Hou, Xinmin Total domination in the Cartesian product of a graph and \(K_2\) or \(C_n\). (English) Zbl 1242.05208 Util. Math. 83, 313-322 (2010). Summary: Let \(G\square H\) denote the Cartesian product of graphs \(G\) and \(H\) and \(\gamma_t(H)\) denote the total domination number of \(H\). We characterize all graphs \(H\) which satisfy \(\gamma_t(K_2\square H)= \gamma_t(H)\) and \(\gamma_t(C_n)\gamma_t(H)= 2\gamma_t(C_n\square H)\), respectively.
