Full Description
This book finds peer-reviewed and edited papers on current topics in number theory. This book, the seventh in a series from the Combinatorial and Additive Number Theory (CANT) conferences, is based on talks from the 22nd and 23rd annual workshops, held in New York in 2024 and 2025, respectively. Organized every year since 2003 by Mel Nathanson at the CUNY Graduate Center, the workshops survey state-of-the-art open problems in combinatorial and additive number theory and related parts of mathematics.
This selection of articles is of relevance to both researchers and graduate students interested in current progress in number theory.
