After many successful Copper Mountain Conferences on Iterative and Multigrid Methods, we have made the difficult decision that it is time to continue the conference series in a new venue. Thus, it is with great pleasure that we announce the 41st Colorado Conference on Iterative and Multigrid Methods, to be held June 21-26, 2026 in Boulder, Colorado, on the CU Campus. We hope to continue the many wonderful traditions of Copper Mountain, with a rich technical problem, opportunities for informal discussion and work time amongst the participants, and a focus on student and early career participants. We are currently finalizing many details for the conference, and information about participation, registration, and lodging will be forthcoming at https://urldefense.us/v3/__https://coloradoconference.github.io/2026/__;!!G_... . Expect student paper competition deadlines in February, 2026, and abstract and registration deadlines in Spring, 2026. We look forward to welcoming you in Boulder!
