Rate My Professor Christian Haesemeyer

Haesemeyer has produced a substantial body of work documented in high-impact publications. He co-authored the book 'The Norm Residue Theorem in Motivic Cohomology' with Charles A. Weibel, published in 2019 by Princeton University Press as part of the Annals of Mathematics Studies series. His papers feature in premier journals including Annals of Mathematics, Inventiones Mathematicae, Journal of the American Mathematical Society, Mathematische Annalen, Journal für die Reine und Angewandte Mathematik, Journal of Algebraic Geometry, Transactions of the American Mathematical Society, Proceedings of the American Mathematical Society, Duke Mathematical Journal, and K-Theory. Selected publications encompass 'Cyclic homology, cdh-cohomology and negative K-theory' (Annals of Math., 2008, with G. Cortiñas, M. Schlichting, C. Weibel), 'Bass’ NK groups and cdh-fibrant Hochschild homology' (Inventiones Math., 2010, with G. Cortiñas, M. E. Walker, C. Weibel), 'K-regularity, cdh-fibrant Hochschild homology, and a conjecture of Vorst' (J. Amer. Math. Soc., 2008, with G. Cortiñas, C. Weibel), 'Techniques, computations and conjectures for semitopological K-theory' (Math. Ann., 2004, with E. M. Friedlander, M. E. Walker), and series on the K-theory of toric varieties and schemes (2009–2018, with G. Cortiñas, M. E. Walker, C. Weibel). Recent preprints include 'K_2-regularity and normality' (2025, with C. Weibel) and 'Module structure of the K-theory of polynomial-like rings' (2025, with C. Weibel). Through these contributions and collaborations with distinguished mathematicians, Haesemeyer has advanced the understanding of K-theoretic invariants in algebraic geometry and topology.
