AYYASWAMY, S.K  y  NATARAJAN, C. On graphs whose chromatic transversal number is two. Proyecciones (Antofagasta) [online]. 2011, vol.30, n.1, pp. 59-64. ISSN 0716-0917.  http://dx.doi.org/10.4067/S0716-09172011000100006.

In this paper we characterize the class of trees, block graphs, cactus graphs and cubic graphs for which the chromatic transversal domination number is equal to two.
