Homogenization of the Neumann-Fourier Problem in a Thick Two-Level Junction of Type 3:2:1

We consider a mixed boundary-value problem for the Poisson equation in a two-level junction " which is the union of a domain Ω₀ and a large number of thin cylinders with cross-section of order O(ε²): The thin cylinders are divided into two levels depending on their lengths. In addition, the t...
