Magnetic resonance assessment of the effect of maternal position on fetoplacental blood flow and oxygenation

A compact Riemann surface is called pseudo-real if it admits anti-conformal (orientation-reversing) automorphisms, but no anti-conformal automorphism of order 2, or equivalently, if the surface is reflexible but not definable over the reals. It is known that there exist pseudo-real surfaces of genus g for every integer g≥2, and the number of automorphisms of any such surface is bounded above by 12(g−1).In this paper, we extend the concepts of...
