Fields medalists 2022

Recently the Fields medalists 2022 (and all the other prizes given out by the IMU) were announced: official page. You can read about some of the achievements of these people on the blog of Gil Kalai (and of course also in the official laudationes).

Shaw Prize 2022

The Shaw Prize in Mathematical Sciences 2022 (link) is awarded to Noga Alon and to Ehud Hrushovski for their remarkable contributions to discrete mathematics and model theory with interaction notably with algebraic geometry, topology and computer sciences.

A quantitative coarse obstruction to psc-metrics

Recently, Guo and Yu pushed the following result to the arXiv (math.KT/2203.15003): For any \(R > 0\) and positive integer \(m\), there exists a constant \(k(R,m)\) such that the following holds. If \((M,g)\) is a Riemannian spin manifold that admits a uniformly bounded, good open cover with Lebesgue number \(R\) and \(R\)-multiplicity \(m\), then \[\inf_{x \in M} \kappa_g(x) \le … Continue reading "A quantitative coarse obstruction to psc-metrics"

Abel Prize 2022

The Abel Prize 2022 was awarded to Dennis Sullivan “for his groundbreaking contributions to topology in its broadest sense, and in particular its algebraic, geometric and dynamical aspects”.

ICM 2022 takes place as a fully virtual event

The International Mathematical Union announced that the International Congress of Mathematicians 2022 will not be held in Saint Petersburg but will take place as a fully virtual event instead. The participation will be free of charge. The full statement can be found here.

Mathematikleistungen von Schüler*innen der gymnasialen Oberstufe

Im Journal für Mathematik-Didaktik ist letztes Jahr ein Artikel von Rolfes-Lindmeier-Heinze erschienen (DOI:10.1007/s13138-020-00180-1), welcher die seit 1995 durchgeführten Schulleistungsuntersuchungen zu Mathematikleistungen in der Oberstufe einer Sekundäranalyse unterzieht, d.h. auf vergleichbare Skalen transformiert und vergleicht. Viele Dozierende in den MINT-Fächern klagen bei Studienanfänger*innen über schlechte Mathematikkenntnisse und es wird auch ein Verfall dieser über die letzten … Continue reading "Mathematikleistungen von Schüler*innen der gymnasialen Oberstufe"
