Light Curves of Microlensed Type Ia Supernovae
  A detailed description of the apparent light curves of microlensed SNe Ia as extended and expanding sources is presented. We show that microlensing amplification can have significant effects on supernova observation. A model light curve is used to compare lensed and unlensed cases and we find that significant changes in shape can occur because of microlensing. We briefly discuss the probability of observing such effects as well. Throughout the paper we consider the redshift of the source to be 1.0 and we limit our work to spherically symmetric deflectors.
