Explore gamma convergence in this comprehensive lecture from the International Centre for Theoretical Sciences' program on Multi-Scale Analysis and Theory of Homogenization. Delve into minimization problems, coercivity, and lower semi-continuity concepts. Examine integral functions, weak lower semi-continuity, and their applications in homogenization theory. Work through exercises and problem-solving sessions to reinforce understanding of these advanced mathematical concepts. Gain insights into recent developments and ongoing research in multi-scale analysis, preparing you for further study or collaboration in this field.
