Advanced chapters from inverse problem theory.

Solution of the inverse problem in general L_p norm. Least absolute value criterion. Linear programming, FIFO, simplex method. Minimax. Adjoint problems and their applications. Introduction to data assimilation.

Practical applications

Seismic location. Seismic tomography. Magnetotelluric inversion. Gravimetric inversion Data assimilation based on Kalman filtering. Different approaches and techniques will be tested on real-life geophysical examples.
