The book introduces main mathematical models describing mechanical behavior at microscopic level of heterogeneous media and for blood flow in a network of vessels. Homogenization technique is applied for multiscale analysis of heterogeneous media. For the network of vessels, asymptotic methods (matching, boundary layers) are presented. The method of asymptotic partial decomposition of the domain defines hybrid dimension models combining one-dimensional (1-D) description obtained from the dimension reduction with three-dimensional (3-D) zooms. It justifies the special exponentially precise junction conditions at the interface of 1-D and 3-D parts. It can be applied to model the blood flow in vessels with a thrombus or a stent. The course contains an important introductory part recalling the necessary mathematical background so that it is accessible not only for the masters and Ph.D. students in mathematics but also for those in engineering and biophysics.The structure of the book is as follows. The first chapter introduces the main equations of mathematical physics. These equations are derived from the conservation laws. The main types of boundary conditions are introduced. The second chapter contains the minimal mathematical background which is required for better understanding of the multiscale methods. It recalls the main notions of analysis, . These theorems are used to prove the error estimates for the multiscale approximations.The third chapter introduces the homogenization technique as a general method used to pass from the microscopic scale to the macroscopic scale. First, this method is presented for a 1-D heat equation. Then, a similar presentation is developed in the case of the conductivity equation in multiple dimensions.Then, the error estimates are derived for the approximations of the homogenization method. These estimates are crucial to persuade the users that the method is effective and to fix the limitations of the theory. Next page
