We consider real algebraic varieties that are intersections of three real quadrics. For brevity they are referred to as real triquadrics. We construct triquadrics that are $M$-varieties and calculate the cohomology groups of the real parts of such triquadrics with coefficients in the field of two elements using relations between triquadrics and plane curves.
Keywords: maximal varieties, theta-characteristics, spectral curve.
Mots-clés : triquadrics
