Absolute versus relative measurements in geometry | Rational Geometry Math Foundations 134
In science and ordinary life, the distinction between absolute and relative measurements is very useful. It turns out that in mathematics this is also an important distinction. We must be prepared that some aspects of mathematics are more naturally measured relatively, rather than absolute

Johan de Jong - Affineness of the complement of the ramification locus - WAGON
The purpose of this talk is to encourage people to think about purity questions. We will discuss a strong form of purity for morphisms of relative dimension 0. For morphisms of relative dimension 1 we relate the purity question to one on purity for families of curves.

Projectivity of the moduli space of KSBA stable pairs and applications - Zsolt Patakfalvi
Zsolt Patakfalvi Princeton University February 24, 2015 KSBA (Kollár-Shepherd-Barron-Alexeev) stable pairs are higher dimensional generalizations of (weighted) stable pointed curves. I will present a joint work in progress with Sándor Kovács on proving the projectivity of this moduli spac

Absolute vs. relative Gromov-Witten invariants - Tehrani
Topic: Absolute vs. relative Gromov-Witten invariants Speaker: Mohammad Tehrani Date: Friday, December 18 We compare absolute and relative Gromov-Witten invariants with the basic contact vector for very positive divisors. For such divisors, one might expect that these invariants are the s

Is space-time fragmented, segmented into quantized bits of information, or causal sets? Or is space-time smooth and continuous, with curves, bends, and warps; just as Einstein had predicted? Is what we call space-time even part of objective reality or is it just a mathematical construct
