Popis:	We study neutrino oscillations in background matter within the quantum field theory formalism where neutrino mass eigenstates are virtual particles. In this case, neutrino mass eigenstates are mixed owing to the interaction with matter. Assuming that neutrinos are Majorana particles, we find the exact propagators for massive neutrinos accounting for the interaction with matter by solving the analog of the Dyson equation. These propagators are used to calculate the transition probability which coincides with the prediction of the Mikheyev--Smirnov--Wolfenstein effect. Finally, we analyze the approximations made in our analysis. Comment: 17 pages in pdflatex, 5 pdf figures
