Combinatorial Algebra Meets Algebraic Combinatorics January 25-27, 2019 • University of Ottawa Organizers: Colin Ingalls and Daniel Panario (Carleton University), Franco Saliola (Université du Québec à Montréal), and Alistair Savage (University of Ottawa) This was the 16th iteration of Combinatorial Algebra Meets Algebraic Combinatorics. The goal of these meetings is to advance an ongoing dialogue between researchers in algebraic combinatorics working in combinatorial aspects of representation theory and polyhedral combinatorics, and commutative algebraists with combinatorial interests such as toric geometry and tropical geometry. The interaction between these two groups has proven to be immensely fruitful, leading to a cross-fertilization of ideas. The 2019 event was held at the University of Ottawa. It attracted over 60 participants from across Canada and the United States. As with previous events, the workshop included four invited lectures and a number of shorter contributed talks. Uniquely, this year's event also featured a CRM - University of Ottawa Distinguished Lecture on Gelfand-Tsetlin Theory by Vyacheslav Futorny (University of Sao Paulo). The workshop opened on Friday afternoon with an invited talk by Susan Cooper (University of Manitoba), which was followed by a talk by Erhard Neher (University of Ottawa) and the CRM Distinguished Lecture. The event resumed on Saturday morning with an invited talk by Daniel Erman (University of Wisconsin-Madison) and talks by Adam Van Tuyl (McMaster University), Maryam Ehya (Dalhousie University), Oliver Pechenik (University of Michigan), and Daniele Turchetti (Dalhousie University). The mathematics presented in the morning spurred conversations over lunch in the university dining hall. The afternoon session began with an invited talk by Rosa Orellana (Dartmouth College) and talks by Sara Faridi (Dalhousie University), Michael Reeks (University of Ottawa), Erika Ordog (Duke University), Kaveh Mousavand (Université de Québec à Montréal), and Glenn Appleby (Santa Clara University). Saturday evening featured a conference dinner at Byward Market. Sunday began with an invited talk by Kirill Zainoulline (University of Ottawa), followed by talks by Véronique Bazier- Matte (Université de Québec à Montréal), Yuly Billig (Carleton University), and Nancy Wallace and Hugh Thomas (Université de Québec à Montréal). The workshop was a resounding success, further strengthening the research connections between these two groups of researchers. 15
