Current Research - FOSLL* for the elasticity equation with discontinuous coefficients in 3D.
1. The Elasticity Equation
We consider equation of linear elastic and isotropic materials and apply a time-harmonic vibration through boundary.

2. Least-Squares Method
Mission is to minimize the residual functional which induced by first-order system.
Mission is to minimize the residual functional which induced by first-order system.
3. Simulation of the Elasticity equation
Let coefficients be constant in 2-dimension. Below Matlab GUI gives the simulation of elasticity equation and error-analysis.
4. FOSLL*
Assume that the anomalies be compactly contained which lead to the matrix with discontinuous coefficients.
We suggest the methodology, FOSLL* , to get rid of discontinuity inside of derivatives and to get L2-approximation.
