Thoa Thieu, our Phd student in maths based at GSSI (Gran Sasso Science Institute) in L’Aquila, Italy, visits our group for 1 month. This is the *de facto* starting moment of Thoa on the mathematical analysis of multiscale (hybrid) pedestrian flows.

# Category: Maths

I am a professional mathematician. Here I will be collecting some of my math news.

## Graduation project in Crowd Dynamics (BSc/MSc in CS/maths/phys)

Omar Richardson and I we are searching for motivated BSc and/or MSc students willing to dwell into understanding crowd motion with modern data vizualization techniques, see the call

Just get in touch with us …

## What kind of maths should be taught in high-schools?

This is an apparently simple question, but the answer is not always obvious.

BUT there are things a teacher (or a problem books writer, etc.) should not ask 16 years old kids in regular schools to solve. One example is Exercise 28, on page 55 from the book by Burtea et al. “Matematica: Culegere de probleme, Clasa X, Trunchi comun si diferentiat”, Ed. Carminis, Pitesti, 2005. The exercise asks: “Show that there are no surjective functions between a set A and the set of all its subsets (ususally denoted by P(A)). ” This exercise is nothing else than what 1st year (university) students in mathematics meet in their mathematical analysis course as “Cantor Theorem”, whose proof is based on a not really intuitive contradiction argument. Kids and trainers preparing themselves for the mathematics olympiad may want to prove Cantor’s result by themselves, but all the others should pick other nicer and more accessible math exercises involving surjective functions…

## Michael Eden visits Applied Analysis & KAU

Michael Eden, phd student in PDEs/industrial mathematics won a scholarship to work for 1 month within the Applied Analysis group in Karlstad. Michael is mainly interested in the analysis of free boundary problems in the context of mathematical homogenization settings.

Direct applications of his analysis work are linked to the bainitic phase transformation in steels and their effect on TRIP (transformations-induced plasticity).

## Reading club on “PDEs and Harmonic Analysis”

On August 30, I am starting off a reading club following the lecture notes by Sergiu Kleinerman (Princeton) of a graduate course on “PDEs and Harmonic Analysis”. You are welcome to join!

## Lectures, talks and interviews for the senior lecturership in Maths & Karlstad

Looking forward to see excellent people in action… with the hope to having them with us at Maths & Karlstad.

## New planning of the mathematics club – see Elisabet Mellroth’s blog

For the interested children (and parents), visit http://www.pedagogvarmland.se/blogg/342

## Possibility for a PhD scholarship in applied mathematics (La Sapienza univ., Rome and Karlstad univ., Sweden)

Excellent MSc students in mathematics and/or theoretical physics willing to work together with me and Prof. Emilio Cirillo (SBAI, Rome, http://www.sbai.uniroma1.it/~emilio.cirillo/index.php) for a PhD thesis at the border between probability theory and mathematical analysis are invited to contact either me or Emilio asap.

The call for applications is: https://cofund.altamatematica.it/dp-2015/main/website

## 7th Workshop in Kinetic Theory and Applications in Karlstad (June 2017)

During June 19-21, 2017, the 7th workshop in kinetic theory and applications will be hosted by the Department of Mathematics and Computer Science of Karlstad University.

Fans of Boltzmann-like equations feel welcome to join!

## Call for Papers: Multiscale Inverse Problems (Applicable Analysis, Taylor Francis)

The special issue focuses mainly on multiscale aspects of numerical and mathematical analysis of inverse problems.

Topics include:

- Inverse problems
- Multiscale deterministic and stochastic PDEs
- Identification problems related to sparse and coherent multiscale large data
- Applications to mathematical foundations of material sciences
