  An overview of the theoretical status of the top quark and single-jet
inclusive production cross sections at the Tevatron is presented. NLO results
as well as NNLO-NNLL and higher order threshold expressions derived from
resummation calculations are discussed. Numerical results are presented for top
quark production at the Tevatron, and it is shown that higher orders contribute
sizable corrections to the total cross section and differential distributions,
and they also dramatically reduce the factorization scale dependence of the
cross section. For jet production, the scale dependence is also reduced but the
NNLO threshold corrections are not very big.
