"38th Days of Weak Arithmetics" 2019 Conference

Country: USA

City: New York

Abstr. due: 02.04.2019

Dates: 28.05.19 — 30.05.19

Area Of Sciences: Physics and math;

Organizing comittee e-mail: cegielski@u-pec.fr

Organizers: City University of New York

 

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.
