SUMMARY: (...): Quantitative imaging technique using an adaptive finite ele
 ment method
DESCRIPTION:: We will discuss solution of coefficient inverse problems (CIP
 s) where the goal is to reconstruct the spatially distributed coefficients
  in different hyperbolic PDE (acoustic\, elastodynamic and electromagnetic
 ) using Lagrangian approach and an adaptive finite element method (AFEM).
   We will present theoretical results which justify why we canimprove sol
 ution of our CIPs using AFEM.  We also will present general approach for 
 derivation of a posteriori error estimates for the error in the Tikhonov f
 unctional\, Lagrangian and the coefficient to be reconstructed.-At the end
  of the talk we will present numerical examples which will demonstrate eff
 iciency of application of an adaptive FEM for solution of different hyperb
 olic CIPs: in the reconstruction of coefficients in Maxwell's equations an
 d in the computational design of approximate cloaking.[http://www.math.cha
