A huge shock, and a massive loss for our field. Vladimir contributed so much to what the field is today. Most obviously, with his own direct contributions and early insights into working in type theory without UIP; also through his influence within the field, with a strong and well-articulated vision of topics he felt were important to work on (most concretely, directing and co-ordinating the work of many contributors in the UniMath library); and of course also through his outreach to a wider mathematics audience, helping to put type theory and formalisation on the radar of many people who otherwise might not have given it attention or interest. He was always stimulating and insightful, if not always easy to work with — extremely mathematically exacting. His views and goals were often idiosyncratic and surprising, but always came from extremely well-thought-out mathematical grounds, that one might disagree with but could never dismiss. We’ve lost a huge contributor and leader in the field, and will all be the poorer for it. –Peter. On Sun, Oct 1, 2017 at 6:54 AM, Daniel R.
