SIAM Conference on Analysis of Partial Differential Equations (PD19)

The primary goal of this conference is to bring together scientists and mathematicians working in partial differential equations and related fields. Contemporary challenges raised by recent advances in engineering, industry, and biotechnology, will be confronted with stateoftheart mathematical and computational tools in PDE. Some of the topics covered in this meeting can be found in the list of themes below. Advanced graduate students and young researchers are encouraged to participate. Limited funding is available for graduate students and recent PhDs.

Math shows why animals see at night

By combining mathematics with science, an interdisciplinary team at Hiroshima University (HU) found how changes in the shape of DNA structure affect the nuclei of nocturnal animals. Their findings could help explain how nocturnal animals, such as mice, see at night.

Scientists measure precise proton radius to help resolve decadeold puzzle

York University researchers have made a precise measurement of the size of the proton  a crucial step towards solving a mystery that has preoccupied scientists around the world for the past decade. The world's physicists have been scrambling to resolve the protonradius puzzle. Now, a study to be published in the journal Science finds a new measurement for the size of the proton at 0.833 femtometers, which is just under one trillionth of a millimeter.

How do social networks shape political decisionmaking?

New research shows that social media's influence on voting goes beyond bots and foreign interference. A mathematical biologist from the University of Houston and his colleagues found that even subtle changes in the algorithms that determine what you see in your social media feeds can have a profound effect on voting outcomes.


'Information gerrymandering' poses a threat to democratic decision making, both online and off

Concern over fake news and online trolls is widespread and warranted, but researchers led by the University of Pennsylvania's Joshua Plotkin and the University of Houston's Alexander Stewart have identified another impediment to the free flow of information in social networks. The phenomenon, which they term "information gerrymandering," arises from the structure of a social network and introduces bias into collective decisions.

European research grant for Bielefeld mathematician

The European Research Council (ERC) has awarded an ERC Starting Grant to the Bielefeld mathematician Dr Dawid Kielak for his innovative approaches to research on geometric group theory, a field of mathematics. The European Union uses this award to promote earlycareer scientists with an excellent scientific track record who also show great promise. Dawid Kielak's research will receive roughly 1.5 million euro over a period of 5 years.

Novel math could bring machine learning to the next level

In recent years, a theory called 'Topological Data Analysis,' stemmed from a branch of Mathematics so abstract that it did not seem to have any application whatsoever in the real world, has been making computers much better at recognizing meaningful structure inside all kinds of large datasets (a.k.a. 'big data'). A new study now shows that it could also make machine vision much more efficient.
