## Abstract Every compact symmetric bilinear form __B__ on a complex Hilbert space produces, via an antilinear representing operator, a real spectrum consisting of a sequence decreasing to zero. We show that the most natural analog of Courant's minimax principle for __B__ detects only the evenly in
