Title
Monochromatic triangles in three-coloured graphs
Abstract
In 1959, Goodman [9] determined the minimum number of monochromatic triangles in a complete graph whose edge set is 2-coloured. Goodman (1985) [10] also raised the question of proving analogous results for complete graphs whose edge sets are coloured with more than two colours. In this paper, for n sufficiently large, we determine the minimum number of monochromatic triangles in a 3-coloured copy of K"n. Moreover, we characterise those 3-coloured copies of K"n that contain the minimum number of monochromatic triangles.
