minimax principle; minimax inequality; weakly lower semicontinuous functions; concave functions
The author answers an open question formulated by B. Ricerri. Namely, he shows that in the minimax inequality required for applying Ricerri's minimax principle the term expressed with a continuous and concave function on an interval can be always described by means of a linear function.
