DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UNYONTC/16/"
 >Local-global principles over semi-global fields</a>\nby David Harbater as
  part of Upstate New York Online Number Theory Colloquium\n\n\nAbstract\nL
 ocal-global principles have classically been studied in the \ncontext of g
 lobal fields\; i.e.\, number fields or function fields of \ncurves over fi
 nite fields.  In recent years\, they have also been studied \nover what ha
 ve come to be known as semi-global fields\, a class that \nincludes functi
 on fields of p-adic curves. Classical results such as the \nHasse-Minkowsk
 i theorem have been carried over to this context\, though \nwith very diff
 erent proofs. The talk will present results in this \ndirection\, includin
 g ongoing work of the speaker with J-L. \nColliot-Thélène\, J. Hartmann\
 , D. Krashen\, R. Parimala\, and V. Suresh.\n
