PERIOD: FEBRUARY The course is based on the courses given for the master and Ph.D. students in 2015‐2018 at Skoltech (Moscow), University of Chile (Santiago), University of Lyon (University Jean Monnet). The course introduces main mathematical models describing mechanical behavior at microscopic level of heterogeneous media and for blood flow in network of vessels. The homogenization technique is applied for multiscale analysis of heterogeneous media. For the network of vessels the asymptotic methods (matching, boundary layers) is presented. The method of asymptotic partial decomposition of the domain defines hybrid dimension models combining one‐dimensional description obtained by the dimension reduction with three‐dimensional zooms. It justifies the special exponentially precise junction conditions at the interface of 1D and 3D parts. It can be applied to model the blood flow in vessels with trombs or stents. (more

"Multiscale mathematical modeling in engineering, biology and medicine" by Grigory Panasenko (CMM and University of Lyon) 1) Introduction to the main equations of mathematical physics used in the mathematical modeling and boundary and initial conditions.  Diffusion‐convection equation  Viscous flows equations (Navier‐Stokes equations, Stokes equations, nonnewtonian flows)  Elasticity equations, visco‐elasticity equations  Dirichlet's, Neumann's, Robin's and periodic boundary conditions; number of initial conditions; periodic in time problems Derivation from physic laws (ideas) and notion of mathematical analysis (weak formulation, existence, uniqueness and stability of the solution, i.e. wellposedness). 2) Modeling of composite materials and meta‐materials. Homogenization technique in mechanics of solids: passage from microscopic scale to the macroscopic scale. 3) Models of flows. Thin tube structures and multi‐structures. Asymptotic analysis. Method of partial asymptotic decomposition of the domain for flows in a tube structure with rigid walls. Elastic and viscoelastic walls of the flows: special boundary conditions for the fluid.
