Mathematics and Geosciences ― Global and Local Perspectives

This is the second volume of the topical issue “Mathematics and Geosciences: Global and Local Perspectives” which embraces 21 papers on different topics relating to Mathematics and Geosciences. They address different topics under both global and local perspectives, such as a method for calculating probabilities for large events in systems such as earthquakes, typhoons, etc.; the use of the Laplace–Fourier-domain full waveform inversion technique to deep-sea seismic data; discrete element modeling; step-edge detection filters, study of a transition zone of the Narmada-Son lineament; integral formulae for recovering the sub-crustal stress from terrestrial gravimetric data; numerical simulations of earthquake fault systems and their use to estimate gravity changes; application of Gaussian clustering to joint interpretation of seismic and magnetotelluric data; on the reliability and fidelity of archaeomagnetic and volcanic records to recover the past evolution of the Earth’s magnetic field; the study, for the first time, of variations in absolute surface geostrophic currents (SGC) using satellite data only; discussion of the inconsistency of IAU2000 non-rigid earth nutation model; the study of nonlinear anisotropic diffusive filtering applied to the ocean’s MDT; the numerical solution of a nonhydrostatic ocean model; Hydrological-Hydraulic models; Steiner rearrangement of a function to study the effectiveness of chemical reactors for the treatment of wastewaters; GNSS software; the study of the fractal dimensions for the identification of bedrock lithology; the study of the Uruk archaeological site (southern Iraq) by integrated geophysical methods; mathematical model for patchy landscapes; study of pore space soil structure; and the results of comparison between transverse electric-type fields and between transverse magnetic and transverse electromagnetic fields.
