The ubiquity of Psi-matroids
Nathan Bowler, Johannes Carmesin
Solving (for tame matroids) a problem of Aigner-Horev, Diestel and Postle, we prove that every tame matroid M can be reconstructed from its canonical tree decomposition into 3-conn…
Infinite Matroids and Determinacy of Games
Nathan Bowler, Johannes Carmesin
Solving a problem of Diestel and Pott, we construct a large class of infinite matroids. These can be used to provide counterexamples against the natural extension of the Well-quasi…
An excluded minors method for infinite matroids
Nathan Bowler, Johannes Carmesin
The notion of thin sums matroids was invented to extend the notion of representability to non-finitary matroids. A matroid is tame if every circuit-cocircuit intersection is finite…
A characterization of the locally finite networks admitting non-constant harmonic functions of finite energy
Johannes Carmesin
We characterize the locally finite networks admitting non-constant harmonic functions of finite energy. Our characterization unifies the necessary existence criteria of Thomassen a…
