A nowhere-zero k-flow is a mapping of values ±1, ±2, . . . , ±(k − 1) to darts of a graph satisfying Kirchhoff’s law – the inflow is the same as the outflow – for every vertex of the graph. It is conjectured [Tutte, 1954] that each bridgeless graph has a nowhere-zero 5-flow. Almost three decades later, Seymour [Seymour, 1981] made a general construction of nowhere-zero 6-flow from a 2-flow and a 3-flow. Although these two flows permit zeroes, no edge can have both of them equal to zero simultaneously. In a recent preprint [Gáborik et al., 2025], along with the introduction of two-dimensional Chebyshev nowhere-zero flows, the authors showed a similar construction of the nowhere-zero 5-flow from a 2-flow and a 4-flow. In addition to forbidding simultaneous zero values, the flow values (0, 1) and (0, −1) are also excluded. This structure is called a 1/2-flow-pair. In this talk, we explore the properties of 1/2-flow-pairs. We prove their existence on snarks with oddness 2, and we also show that one can construct a rich nowhere-zero 7-flow from them. We also use a generalised version of the 1/2-flow-pair to investigate the Chebyshev flow number and to show that the 2-dimensional Chebyshev flow number of snarks can be arbitrarily small.

Abstrakt:
In this talk, we discuss ultrafilters and their role in combinatorics, topological algebra and set theory. In particular, we present some classical combinatorial results that can be proven using idempotent ultrafilters. We introduce Schur ultrafilters and describe their relationship to P-points and Ramsey ultrafilters. Using Schur ultrafilters we give a new representation of Bohr compactifications of topological groups, and characterize automatic continuity of group operations in certain compact right topological groups. Finally, we present a topological counterpart of Hindman's theorem which addresses colorings of topological groups. The talk is intended to be self-contained and accessible to a broad mathematical audience. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Macaj@fmph.uniba.sk Tue, 07 Apr 2026 14:19:00 +0200 http://39417 v pondelok 13.4.2026 o 15:00 hod. v posluchárni C [FMFI] Kalendár Robert.Kysel@fmph.uniba.sk Tue, 07 Apr 2026 13:56:00 +0200 http://https://www.expres.sk/377064/zverejnenie-detailov-o-poskodenom-ropovode-druzba-by-predstavovalo-bezpecnostne-riziko/ Politológ Jozef Bátora z Filozofickej fakulty UK komentuje v Rádiu Expres aktuálny vývoj vojny na...
