Research Directions in Number Theory: Women in Numbers IV (Association for Women in Mathematics Series Book 19)

"These proceedings collect several number theory articles, most of which were written in connection to the workshop WIN4: Women in Numbers, held in August 2017, at the Banff International Research Station (BIRS) in Banff, Alberta, Canada. It collects papers disseminating research outcomes from collaborations initiated during the workshop as well as other original research contributions involving participants of the WIN workshops. The workshop and this volume are part of the WIN network, aimed at highlighting the research of women and gender minorities in number theory as well as increasing their participation and boosting their potential collaborations in number theory and related fields." - Prové de l'editor Front Matter ....Pages i-xix Ramanujan Graphs in Cryptography (Anamaria Costache, Brooke Feigon, Kristin Lauter, Maike Massierer, Anna Puskás)....Pages 1-40 Cycles in the Supersingular l-Isogeny Graph and Corresponding Endomorphisms (Efrat Bank, Catalina Camacho-Navarro, Kirsten Eisenträger, Travis Morrison, Jennifer Park)....Pages 41-66 Chabauty–Coleman Experiments for Genus 3 Hyperelliptic Curves (Jennifer S.
