### Top Quark Production at D0.

Karel Soustruznik
We present measurements of the production cross sections of top-antitop quark pair via the strong interaction and of single top quark via the weak interaction in proton-antiproton collisions at sqrt(s)=\unit{1.96}{\TeV} using data corresponding to integrated luminosities up to \unit{5.4}{\invfb}. The data were collected with the D0 detector at the Fermilab Tevatron collider. We also present measurements of the forward-backward asymmetry in the top-antitop quark final states.
