V. A. Krasnov P. G. Demidov Yaroslavl State University
Abstract:
Nonsingular intersections of three real six-dimensional quadrics are considered. Such algebraic varieties are referred to for brevity as real four-dimensional triquadrics. Necessary and sufficient conditions for a real four-dimensional triquadric to be a $\mathit{GM}$-variety are established.
Keywords:
six-dimensional quadric, $\mathit{GM}$ variety, triquadric, spectral curve, spectral bundle, index function, cohomology group, Stiefel–Whitney class.
