# Mathematical and Numerical Methods in solid Earth Physics

## Overall Course Objectives

The course aims to provide basic mathematical tools for solving numerical problems in space and geophysics. In particular, the course will focus on using Matlab to solve general mathematical problems. However, student may use python to solve problems.

Learning Objectives

• explain the concepts tensor, tension, deformation, external forces, constitutive relationships
• explain fundamental concepts in connection with interpolation, projection, including kriging, simulation, semi-variogram, correlation, area/distance/angle conservation
• solve simple linear and non-linear inverse problems in 1D and 2D
• solve problems regarding static pressure and stress conditions, flow phenomena in the ocean and in the earth
• solve problems regarding plastic flow in ice caps and flow in porous media
• solve problems concerning transformations between geodetic coordinate systems (ITRF, EUREF)
• analyze time series and calculate the corresponding uncertainty
• program in Matlab (or Python) and compile complex code to solve numerical integration in connection with geophysical problems
• use Matlab (or Python) to construct animations/videos in connection with the dissemination of geophysical problems.

Course Content

Introduction to Cartesian tensors, stress, strain, volume forces, deformation, and rotation. Advanced programming in Matlab. Introduction to numerical methods for projection and transformations with distance, area and/or angle conservation. Introduction to linear and non-linear inverse problems in 1D and 2D. Analysis of time series and uncertainty and interpolation in 1D g 2D using kriging. Examples of equations of motion and conservation of mass/flux.
