Mathematical Modelling: Analysis and Applications
This course provides introduction of mathematical modeling and analysis in biological sciences. It is designed for students in both applied mathematics and bio-medical / biological sciences. The major content of this course is chosen from population dynamics. This course covers the fundamentals of deterministic models in both discrete and continuous time domain. This course includes both linear and non-linear models with sufficient amount of theoretical background. The relevant concepts and solution methods of various difference and differential equations are provided. We have also focused on graphical solution for clear analysis of nature of models.
INTENDED AUDIENCE:UG/PG students of technical universities/colleges
PREREQUISITES: Basic Calculus
INDUSTRY SUPPORT :Nil
