DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AppliedMath/
 11/">Homogenization in evolving porous media</a>\nby David Wiedemann (Univ
 ersitaet Augsburg) as part of SFU Mathematics of Computation\, Application
  and Data ("MOCAD") Seminar\n\n\nAbstract\nNumerical simulations of physic
 al or chemical processes in heterogeneous \nmedia require a resolution of 
 the heterogeneous structure. If\, however\, \nthis heterogeneity is micros
 copically small while the object under \nconsideration is large\, a dimens
 ional mismatch occurs and classical \nnumerical methods become infeasible.
 \n\nAt this point\, analytical homogenization provides effective homogeneo
 us \nsubstitute models\, which can be simulated numerically much more easi
 ly. \nOne class of problems that can be treated are processes in porous me
 dia. \nIn many biological or chemical applications\, the pore structure ev
 olves \nin time\, which impedes classical homogenization. By means of the 
 \ntwo-scale transformation method\, we can overcome this difficulty and \n
 derive new effective models for problems in evolving heterogeneous media.\
