We are pleased to invite you to the 2023 edition of the West Coast Number Theory (WCNT) Conference (the 54th such conference). WCNT is an informal meeting encouraging number theorists to discuss problems of interest in number theory. It consists of three main components: a series of short (15 to 20-minute) talks for presenting results of interest to number theorists, problem sessions, interactive question-and-answer sessions for discussing problems of interest to number theorists, and community sessions, themed sessions where we dig into relevant but “non-mathematical” problems of interest to number theorists (i.e. non-traditional careers in number theory, work-life balance).
