Weak Arithmetics Days

JAF 38

May 28-30 2019, The Graduate Center

City University of New York

Call for Participation

Aim: Weak Arithmetics play a fundamental role in several areas of philosophy, mathematics, and computer science by studying the nature and properties of natural numbers from a logical point of view.  The aim of the conference is to provide a forum for researchers to present their results to members of communities who study or apply weak arithmetics in various fields and formalisms.
