António Carlos Henriques Guedes de Oliveira's Annual Report
Year:
2014
Brief description of the research activities:
In co-work with Rui Duarte, I obtained a bijective proof of the Theorem of Hajós on the convolutions of the centreal binomial coefficients, the first one in leitterature not based in lattice paths. This work was published in the Journal of Integer Sequences.
We also continued previous work on the Pak-Stanley bijection, noe extended to other arrangements.
