Fano Surfaces of Real Quartics
V. A. Krasnov P. G. Demidov Yaroslavl State University
Abstract:
We prove certain properties of the Fano surface of bitangents to the real quartic in projective 3-space. In particular, we estimate the dimension of the cohomology of the real part of this surface
in terms of the dimension of the cohomology of the real part of the quartic, and compute its Euler characteristic.
Keywords:
real algebraic varieties, quartic, Fano surface, Euler characteristic.
