On the Asymptotic Size Distortion of Tests When Instruments Locally Violate the Exogeneity Assumption
Shinichi Sakata:
Instrumental Variables Estimation and Weak-Identification-Robust Inference Based on Conditional Quantile Restriction
A journey from the Mobius strip, though affine Kac-Moody and superconformal algebras, to children's drawings.
Abstract: One of the most recurrent themes in both Physics and Mathematics, is the study and construction of objects that locally look the same. I will explain, mainly via examples and in non-technical terms, how the concept of "locally look the same" has evolved through time (mostly through some beautiful ideas of Serre and of Grothendieck).
Equivariant Lefschetz invariants via analysis
The PNWNAS has been an annual event since 1987, held on a Saturday each fall.

The mathematical community is recognizing that besides being a valuable numerical and experimental tool, computation is an important object of mathematical study in its own right and an important theoretical tool as well as a source of new and exciting problems for mathematics. The objective of this workshop is to address the opportunity to further the development of the relationship between number theory, experimentation, and computation and to shape the mathematical framework in which the intellectual content of this relationship is studied. We will concentrate our workshop in the areas of the arithmetic of curves over number fields, special values of L–series, diophantine equations, the LLL algorithm, Mahler measure, irreducibility and related problems.
