%0 Report %D 2018 %T Transmission conditions obtained by homogenisation %A Gianni Dal Maso %A Giovanni Franzina %A Davide Zucco %X We study the asymptotic behaviour of solutions to variational problems in perforated domains with Neumann boundary conditions. We consider perforations that in the limit concentrate on a smooth manifold. We characterise the limits of the solutions and show that they solve a variational problem with a transmission condition across the manifold. This is expressed through a measure on the manifold, vanishing on sets of capacity zero. Then, we prove that every such measure can be obtained by homogenising suitable perforations. Eventually, we provide an asymptotic formula for this measure by using some auxiliary minimum problems. %G en %U http://preprints.sissa.it/handle/1963/35310 %1 35618 %2 Mathematics %4 1 %# MAT/05 %$ Submitted by Maria Pia Calandra (calapia@sissa.it) on 2018-03-19T09:23:08Z No. of bitstreams: 1 DM-Fra-Zuc-preprint.pdf: 420855 bytes, checksum: 1c4ce5133a6ab027c50e403c702aa690 (MD5)
