Jaromír Šimša will receive

the Paul Erdös Award of the World Federation of National Mathematics Competitions for 2020; this award is biannually delivered to at most three mathematicians all over the world.

The Paul Erdös Award was established to recognise contributions of mathematicians who have played a significant role in the development of mathematical challenges at the national or international level and which have been a stimulus for the enrichment of mathematics learning.

We warmly congratulate Jaromír Šimša on this outstanding achievement!

Symmetric spaces and their filtered generalizations

Abstract: We focus on the role of symmetries in geometry and geometric control theory. We introduce symmetric spaces as important examples of geometries with many symmetries and we study consequences of existence of special symmetries. Finally we study various generalizations of symmetric spaces.

MUNI Seminar series - Hans Munthe-Kaas - Symmetry - Canceled PDF Print

Canceled

Unfortunately, the speaker Hans Zanna Munthe-Kaas got into the quarantine because of the new coronavirus in recent days and he had to cancel his trip to Brno.

We shall find a new timeslot in the future, but the lecture will not take place this Wednesday.

March 4, 2020 from 4:30 PM at Mendel Museum´s Augustinian Abbey Refectory at Mendel Square

Symmetry: From Conway’s Magic Theorem to Archimedes’ Labyrinth and Beyond

Abstract:
Symmetry is a topic which has inspired artists and mathematicians from ancient to modern times. A fundamental problem is the classification of discrete groups of isometries, such as the 17 planar wallpaper groups, which have been used in mosaics since medieval ages and were classified by Fedorov in 1891 in a complicated proof.

Conway’s Magic Formula can be used to classify discrete symmetries for spherical, plane and hyperbolic surfaces and yields the 17 wallpaper groups, the 7 frieze patterns and all discrete spherical symmetries as special cases. The formula and its proof is so simple that it is accessible to advanced high school students.

Recently, Munthe-Kaas was involved in the design of a mathematical maze in Bergen Botanical garden. Inspired by Conway, he ended up with a highly symmetric design. Under some reasonable assumptions, only one of the 17 wallpaper groups fulfils his original design criteria. The labyrinth, called Archimedes’ labyrint consists of 1234 yews (Taxus baccata, Tis červený) in 2m height and covers an area of about 800 m^2. It was presented in Science Magazine, October 2018.

In the last part of this talk we move beyond Conway, and discuss the problem of multivariate polynomial interpolation. Based on kaleidoscopic symmetry groups (Coxeter groups), we find interpolation points with remarkable properties. We show that for any d and k, there exists a unisolvent set of interpolation points for d-variate polynomial interpolation of order k. These points have optimal Lebesque constants and allow fast computation by symmetric fast Fourier transforms.

Database of mathematical journals at MU PDF Print

A list of electronic math magazines available at MU (more than 650 titles) can be found HERE .

However, magazines from the EBSCO and ProQuest megadablets are not included in this list.

But, it is possible to search for mathematical journals directly in these databases, for example:


EBSCO

http://search.ebscohost.com → EBSCOhost Research Databases → select Publications tab in the top bar → select databases (the most comprehensive is Adamic Search Ulitmate) → in the field Browsing Select By Subject & Description and enter a keyword in the field (eg Mathematics)


PROQUEST CENTRAL

https://search.proquest.com → select Publications in the upper bar → enter a keyword (eg Mathematics) in the search box and choose where we want to search (eg in subject) to Scholarly Journals
