Title: On a theorem of Rademacher-Turán. (In English)
Source: Ill. J. Math. 6, 122-127 (1962).
Review: Non-directed finite graphs without loops and parallel edges are considered. The main result is: there exists a positive constant c1 such that, if t < 1/2 c1n, any graph having n vertices and [ 1/4 n2 ]+t edges contains at least t[ 1/2 n ] triangles. One of the lemma states: if a graph has n vertices and [ 1/4 (n-1)2 ]+2 edges, then either it is even or it contains a triangle. [Reviewer's note: 3 must be added to the left-hand side of the formula (1) on p. 124. This correction does not touch the validity of the further estimations.]
