A finite-dimensional complex space with indefinite scalar product [.,.] having v(-) = 2 negative squares and v(+) greater than or equal to 2 positive ones is considered. The paper presents a classification of operators that are normal with respect to this product. It relates to the study by Gohberg and Reichstein in which the similar classification was obtained for the case v = min{v(-), v(+)} = 1. [References: 1]
