Counterexamples to Orlin’s conjecture on equistable graphs
2014-03-24 10:00-11:00 FAMNIT-SEMIN Martin Milanič Counterexamples to Orlin’s conjecture on equistable graphs A stable set in a graph is a set of pairwise non-adjacent vertices, and a stable set is […]
On cyclic Hamiltonian decompositions of complete k-uniform hypergraphs
2014-03-17 10:00-11:00 FAMNIT-SEMIN Paweł Petecki On cyclic Hamiltonian decompositions of complete k-uniform hypergraphs A decomposition $\mathcal{C}=\{ C_1,C_2,…,C_h\}$ of the complete $k$-uniform hypergraph $K^k_n$ of order $n$ is called {\em cyclic […]

When Hadamard and usual powers coincide?
2013-12-23 10:00-11:00 FAMNIT-SEMIN Bojan Kuzma When Hadamard and usual powers coincide? We classify real matrices where the standard power coincides with the Hadamrad entry-wise. The problem appeared recently in vol 51 […]
