Rainer noticed the pattern halfway through July. He had constructed smooth surfaces in a certain four-dimensional smooth algebraic variety, using the Chern classes of vector bundles. He noticed that he could anticipate these surfaces’ Hodge numbers. “This seems to amount virtually to something like a non-existence result,” he wrote, later that day, in an email to a junior faculty member at another school.
Rainer soon sank into a deep depression. “I go full days without saying a single word,” he told Diego, over the phone. Continue reading
