Some pictures from the SPP Conference in April 2019 in Münster. Let me start with a picture of the speaker of the SPP, Bernhard Hanke, explaining at the beginning of the conference the next steps leading to the second funding period of the SPP. (I unfortunately forgot to take a picture of Carsten Balleier from … Continue reading "Impressions from the SPP Conference"

### Reports on Impact of Mathematics

A week ago the EMS posted links to reports on the impact of mathematical research on society and economy. You can access these reports here: link. Though probably for many too long to read in detail, reading just the introductions is already interesting.

### Multiplying integers

The classical algorithm, that everyone knows from elementary school, for multiplying two n-digit integers runs in $$O(n^2)$$-time. Recently, there was a preprint posted on HAL (link) in which the authors provide an algorithm which runs in $$O(n\log(n))$$-time. A nice article about this discovery may be found at the QuantaMagazine: link. Further, it was also recently proven in another preprint … Continue reading "Multiplying integers"
