Annual meeting of the EU-MATHS-IN and Workshop Mathematics in Industry
The aim of the workshop is to present and discuss examples of good practice in cooperation between industry and academia. Each presentation will consist of a pair of talks on a specific problem given by a mathematician and a representative of industry. Besides mathematical and industrial perspective the speakers are encouraged to describe the genesis and evolution of their project as well as gained experiences and benefits of mutual collaboration.
The series of workshop Mathematics in Industry has been organized in frames of the programme Hopes and Risks of the Digital Era of the Strategy AV21 to foster cooperation between industry and mathematicians working in academia. This workshop has been organized in cooperation with EU-MATHS.IN.CZ, the national part of the European network EU-MATHS-IN which aims to leverage the impact of mathematics on innovations in key technologies by enhanced communication and information exchange between and among the involved stakeholders on a European level. In parallel with the workshop, there will be the annual meeting of the Council of the EU-MATHS-IN as well as the annual meeting of the EU-MATHS.IN.CZ.

Diderot Mathematical Forum: Mathematics and Architecture, 8 June 2019
The cycle of conferences Diderot Mathematical Forum was introduced by the European Mathematical Society in 1996. Each conference takes place simultaneously in three European cities exchanging information by videoconferences, addresses a specific topic, and has both a research and a public component. The venues of the Diderot Mathematical Forum 2019 are Helsinki, Porto and Prague.
The lectures in Prague will take place in the Main Lecture Hall of the Institute of Mathematics CAS on 8 June 2019 from 9 a.m. The speakers include Henri Achten (Czech Technical University), Robert Aish (University College London), Juhani Pallasmaa (Helsinki), Daniel Piker (Foster and Partners), José Pedro Sousa (University of Porto), Christopher Williams (Chalmers University of Technology).
All interested are welcome.

Naši pracovníci se podíleli na nalezení nového typu černé díry
Vědečtí pracovnící našeho ústavu V. Pravda a A. Pravdová ve spolupráci s kolegy R. Švarcem a J. Podolským z MFF UK nalezli statické, sféricky symetrické řešení polních rovnic kvadratické gravitace s nenulovou kosmologickou konstantou popisující černou díru. Tato teorie tedy kromě všeobecně známé Schwarzschildovy černé díry připouští navíc ještě další statickou, sféricky symetrickou černou díru. Ve své práci navázali na práce týmu z USA, Velké Británie a Číny, který s použitím numerických výpočtů existenci této nové černé díry v roce 2015 předpověděl (avšak pouze v případě s nulovou kosmologickou konstantou).
Čeští autoři využili svého předchozího výsledku, ve kterém ukázali, že sféricky symetrické statické prostoročasy jsou vždy konformní ke Kundtovým prostoročasům. Dále také využili toho, že dodatečné členy kvadratické gravitace lze zkombinovat do Bachova tenzoru, který se při konformních transformacích velmi jednoduše transformuje. Tento nový konformní přístup jim umožnil provést podstatnou část potřebných výpočtů "na pozadí" daleko jednoduššího Kundtova prostoročasu a vedl ke dramatickému zjednodušení výsledných polních rovnic kvadratické gravitace. To následně umožnilo zkoumat tyto rovnice analytickými metodami. Ukázalo se, že tato nová černá díra má kromě hmotnosti ještě jeden další parametr, který odpovídá hodnotě Bachova tenzoru na horizontu. V práci bylo také ukázáno, že tento nový parametr má mimo jiné vliv na pohyb testovacích částic obíhajících tuto černou díru.

Learnability can be undecidable
Obor “machine learning” se zabývá zhruba otázkou, co se lze o nějakém objektu dozvědět z omezeného množství dat; v extrémním případě, jestli k uchopení daného problému vůbec stačí konečné množství dat, a pokud ano, kolik. To je dnes zajímavé hlavně kvůli počítačům, ale dalo by se to vnímat i jako studium možností lidského mozku. Ukázali jsme, že poměrně přirozená úloha v tomto oboru je nerozhodnutelná ze základních matematických axiomů. To je zase jiná větev matematiky, matematická logika, která ukazuje, že pravdivost některych tvrzení nelze rozhodnout ze základních axiomů. Klasický příklad je hypotéza kontinua, kdy je nerozhodnutelné, jaká je mohutnost reálných čísel. Podobně my ukazujeme, že obecná otázka, co se lze naučit z konečného množství dat, je nerozhodnutelná. Článek byl publikován v časopise Nature Machine Intelligence.
