Abstract During the past decades, tremendous efforts have been made to develop and analyze mathematical models which describe the dynamical behavior of many human viruses such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and human T cell leukemia virus (HTLV), etc. In this thesis, we use ordinary differential equations (ODEs) and delay differential equations (DDEs) to propose and analyze a class of HIV dynamics models with two types of immune response: humoral immune response and Cytotoxic T lymphocytes (CTL) immune response. . |
