International Society on Loop Quantum Gravity
Mission
Supporting research into the quantum nature of space and time,
and serving the researchers behind.
Quantum gravity aims to combine the lessons of Einstein's general theory of relativity about gravity, space and time with the insights of quantum mechanics. It is expected to lead to new insights into our fundamental understanding of the universe as it unravels the quantum nature of spacetime itself.
Loop Quantum Gravity is a thriving research programme aimed at meeting this challenge. Born as a novel incarnation of the canonical approach to the quantization of General Relativity initiated by DeWitt, Wheeler, Bergmann and other pioneers in the 60s, it has now developed into a diverse set of ideas and perspectives, mathematical techniques and physical directions. The research is carried out by scientists all over the world.
The International Society on Loop Quantum Gravity (ISLQG) is a non-profit organization promoting research in the field of loop quantum gravity and related areas. ISLQG also supports researchers in these fields in carrying out their tasks and in pursuing their careers. Last, but not least, ISLQG seeks to inform the broader public about the fascinating scientific questions and discoveries in the area of gravitational physics and the exciting research carried out presently in loop quantum gravity.
Important areas of activity of ISLQG are supporting the organization of conferences, and more generally, the scientific exchange of its members. For example, the biennial international “Loops” conferences are held under the aegis of ISLQG. The society also aims to provide representation, advice and support for young researchers in the field, to collaborate with other scientific institutions sharing its broad objectives and to promote scientific outreach activities.

In Memory of Prof. Jerzy Lewandowski
Prof. Jerzy (Jurek) Lewandowski has been a towering figure of Polish and international Relativity. He graduated under the supervision of Andrej Trautman, and he worked extensively on isolated horizons and near horizon geometries, loop quantum gravity, CR structures and spacetimes, Einstein equations and the twistor equation. He is credited among the researchers who most contributed to the development of Loop Quantum Gravity, having put his skills as mathematical physicist to the service of many different aspects of the theory. He is equally cherished in the quantum gravity community as somebody who served the community by organizing many conferences and schools, that turned out of particular importance. He has also been the first and long-serving president of the Polish Relativity Society, supporting the study of Einstein's theory in Poland. He has been cherished by colleagues and students for his kind and cheerful spirit, and a unique sense of humor.
In Memory of Sami Viollet
It is with deep sadness that we announce the passing of Sami Viollet, a promising young member of our community, in a mountain accident.

Lewandowski Memorial Conference
In September 2025, the Banach Center in Warsaw organised a conference in memory of Prof. Jerzy Lewandowski (1959–2024). The list of speakers reflected the wide community of researchers with whom Jerzy was in continuous exchange: from students and postdocs to long-term collaborators and world-renowned scientists such as Prof. Abhay Ashtekar,
Prof. Carlo Rovelli and the nobel laureate Prof. Roger Penrose.
