EMS Magazine No. 123

Note that that issue was published before the recent decision to change ICM 2022 into a purely online event, as discussed here (link).

Highlights include:

• A new year message (link) from EMS President Volker Mehrmann, a message from the EMS Executive Committee, and a message regarding predatory publishing practices.

• Jochen Glück on Evolution equations with eventually positive solutions (link). "This eventual positivity phenomenon has recently been discovered for various classes of differential equations, but so far a general theory to explain this type of behaviour exists only under additional spectral assumptions."

• Jean-Paul Allouche writes about T. Tao and the Syracuse conjecture (link). Also known as Collatz's conjecture and the 3x+1 conjecture, this notorious mathematical problem needs no introduction, but has seen some recent progress by Terence Tao. (The EMS thanks La Gazette des Mathématiciens for permission to publish this English translation of an article from April 2021 (link). The author thanks Miriam Gellrich Pedra and Jean-Bernard Bru for their translation.)

• José Francisco Rodrigues discusses Portuguese mathematical typography: A brief overview from 1496 until 1987 (link). The article follows a recent exihibition in Leiria (Portugal), and contains many fascinating photographs of historical documents.

• Tsou Sheung Tsun remembers Andreas Griewank (link), a long-term and valued member of the EMS' s Committee for Developing Countries, who died unexpectedly last September, and is much missed.

• Eugenie Hunsicker reports from the online panel on Gender Balance in Mathematics (link) which took place on 22 June, 2021 as part of the European Congress.

There is much more besides, so please click through (link) and have a read!
