Abstract: We consider non-singular intersections of three real six-dimensional quadrics. They are referred to for brevity as real four-dimensional triquadrics. We calculate the dimensions of their cohomology spaces with coefficients in the field of two elements.
Keywords: triquadric, spectral curve, spectral bundle, index function, index orientation.
