Nonsingular maximal intersections of three real six-dimensional quadrics are considered. Such algebraic varieties are referred to for brevity as real four-dimensional $M$-triquadrics. The dimensions of their cohomology spaces with coefficients in the field of two elements are calculated.
Mots-clés : six-dimensional quadric, triquadric, index orientation
Keywords: spectral curve, spectral bundle, index function, complete involution, cohomology group, Stiefel–Whitney class.
