…nother. For so-called sparse graphs – those in which the number of connections between elements is relatively small – they can be analysed using a well-developed set of tools and methods. The situation is completely different for dense graphs (with many edges): knowledge about them remains incomplete. Prof. Michał Pilipczuk has decided to tackle this challenge.   „We aim to develop a coherent and robust theory describing the structure of dense gra…

…ience, namely the limits of achievability in systems with an infinite number of states. The scientist has become a laureate of a Consolidator Grant awarded by the European Research Council. Prof. Wojciech Czerwiński won his first ERC grant five years ago, as a doctoral candidate. He is now an associate professor and one of ten representatives of the Faculty of Mathematics, Informatics and Mechanics among the winners of this prestigious contest.  …

…ance of admitting the best students to study in Poland and increasing the number of participants in academic exchange programmes was emphasised. Another important element of the conversation was the possibility of Polish academics teaching at Moldovan and Mongolian universities.   During the meeting with the Moldovan ambassador, particular attention was paid to the development of joint activities in the fields of economics and business, engineerin…

…search projects and scientific internships, e.g. in Italy, and her activities also include the commercialisation of research results – she is the co-founder and president of the UW’s spin-off company BHUMI, which develops innovative microbiological preparations for regenerative agriculture and industry.   in the field of social sciences: PROF. JACEK LEWKOWICZ FROM THE FACULTY OF ECONOMIC SCIENCES   He is an expert in institutional economics, econo…

…r knowledge, but remains the only known theoretical explanation of the number of quarks and leptons in the Standard Model. Several years ago, Prof. Krzysztof Meissner from the Faculty of Physics at the University of Warsaw and Prof. Hermann Nicolai from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) went beyond N=8 supergravity and modified the original proposal, obtaining correct electric charges of the Standa…

…However, in real materials, atoms influence each other through short-range dipole-dipole interactions, which are typically neglected in calculations. Research by scientists from the University of Warsaw and Emory University in the USA has shown that dipole-dipole interactions, which are usually neglected, can amplify photons.   „Photons act as mediators, coupling each emitter with all the others inside the cavity,” says Dr João Pedro Mendonça, a…

…This discovery opens up new avenues for research into the social structure, beliefs, and regional contacts of the local population in the 1st millennium BCE.        …

…creasing number of pulses, and the receiver requires precise calibration and stabilization,” says Maciej Ogrodnik.   The new solution developed by researchers from the University of Warsaw avoids these problems. It uses all recorded photon detection events, resulting in significantly higher measurement efficiency. Although the method involves a slightly larger measurement error, this does not hinder the practical implementation of QKD – as confirm…

…UW Rector. At the beginning of the year, an emergency telephone number and a safety website were launched. Pursuant to the rector’s order of 30th June, the Office for Security Affairs was established. Sławomir Obliński is the director of the new unit. “The Office for Security Affairs was established to coordinate all activities related to the protection of the UW community in a consistent and professional manner. We are implementing solutions ada…

The event was organised as part of the celebrations of the 200th anniversary of the Astronomical Observatory of the University of Warsaw.   “On behalf of His Magnificence the Rector, I have the honour of presenting you with a letter of congratulations and expressions of appreciation from the entire Rector’s t…
