Adam Karczmarz (Institute of Informatics)
Shortest paths, edge weights, and models of computation (Najkrótsze ścieżki a wagi krawędzi i modele obliczeń)
Computing the shortest path is one of the simplest optimization problems on graphs. Nevertheless, the exact computational complexity of this problem is not fully understood. The best-known running-time bounds differ depending on the adopted computational …

Partial differential equations with linear growth (Równania różniczkowe cząstkowe z liniowym wzrostem)
In the study of partial differential equations a key question concerns the regularity of solutions and, if the solutions are not smooth enough, finding the precise sense in which the equation is satisfied. The simplest …

When and Why Do Efficient Algorithms Exist (for Constraint Satisfaction and Beyond)?
Some computational problems can be solved efficiently; others seem hopelessly intractable. What accounts for this striking difference? What kind of mathematical structure—or lack thereof—permits efficient algorithms, or conversely dictates computational hardness? Given the vast landscape …

Stability of discontinuous flow for incompressible inviscid fluid (Stability of discontinuous flow for incompressible inviscid fluid)
The compressible Euler equation can lead to the emergence of shock discontinuities in finite time, notably observed behind supersonic planes. A very natural way to justify these singularities involves studying solutions as inviscid limits of …

Contemporary applications of the theory of Fraïssé limits. (Współczesne zastosowania teorii granic Fraïssé'go.)
The construction of the Fraïssé limit of a class of finite (or finitely generated) structures originates from model theory. It turns out that many canonical mathematical objects have such a form, e.g., the rational numbers …

Variational methods in partial differential equations (Metody wariacyjne w równaniach różniczkowych cząstkowych)
Seeking solutions to differential equations as critical points of certain functionals is an important issue in the theory of partial differential equations. Variational methods provide powerful tools for analyzing and solving these equations. The presentation …

Dynamical systems and some problems in complex analysis and geometry (Układy dynamiczne oraz pewne problemy analizy zespolonej i geometrii)
Holomorficzne układy dynamiczne są przedmiotem intensywnych badań od początku lat 80 ubiegłego wieku. Niesłabnąca popularność tej specyficznej gałęzi teorii układów dynamicznych jest (między innymi) motywowana związkiem z problemami geometrycznej teorii funkcji i geometrycznej teorii miary. …

Vector spaces of orbit-finite dimension (Przestrzenie liniowe orbitowo skończonego wymiaru)
Wśród niezliczonych zastosowań przestrzeni liniowych znajdziemy również i teorię automatów. Pomysł jest prosty – normalnie automat ma skończenie wiele stanów, ale za zbiór stanów można też przyjąć przestrzeń liniową skończonego wymiaru. Takie przestrzenie można przeszukiwać …

Classification of smooth manifolds via power series (Klasyfikacja rozmaitości gładkich poprzez szeregi potęgowe)
Opowiem fascynującą historię jak wyniki znane w czysto algebraicznej teorii szeregów potęgowych dwóch zmiennych, zwanych grupami formalnymi, posłużyły Danielowi Quillenowi (medal Fieldsa 1978) do podania zupełnie nowego dowodu twierdzenia René Thoma (medal Fieldsa 1958) o …
