The calculations are performed in Lorentz-invariant baryon chiral perturbation theory. Chiral extrapolation functions for three-flavor unquenched lattice simulations are derived. The matching to the two-flavor case and the sigma terms are also considered.49 pages, 2 eps figuresHigh Energy Physics - LatticeHigh Energy Physics - PhenomenologyNuclear Theorytext
