Supersymmetry seems to facilitate the bringing together of inflationary models with particle physics. We give an overview of inflation models in supersymmetric theories. These models often lead to the production of cosmic strings after inflation. The cosmological implication of the production of these strings strongly depends on whether they saturate the so-called BPS condition. We study a particular model where we show that the BPS condition is preserved at the quantum level. Do not be discouraged by some technical language used in the abstract, all that will hopefully be made clear in more physically transparent terms during the seminar.
