Jacek Jendrej is a Ph.D. student at Ecole Polytechnique advised by Yvan Martel and Frank Merle. He is interested in nonlinear evolution partial differential equations, especially in near-soliton dynamics for critical nonlinearities, energy estimates and compactness methods.

Krzysztof Oleszkiewicz is a professor at the University of Warsaw's Institute of Mathematics, where he received his Ph.D. in 1997 under the supervision of Stanisław Kwapień. His research interests lie in probability theory and analysis, especially in various inequalities, including tail and moment estimates for sums of independent random variables, concentration bounds and hypercontractivity. He has no idea about Computer Science.

Jakub Onufry Wojtaszczyk is a software engineer at Google. Besides developing cluster-level operating systems, he has some knowledge of algorithms and of probability theory.
