WebbPseudo-Anosovs of interval type Ethan FARBER, Boston College (2024-04-17) A pseudo-Anosov (pA) is a homeomorphism of a compact connected surface S that, away from a finite set of points, acts locally as a linear map with one expanding and one contracting eigendirection. Ubiquitous yet mysterious, pAs have fascinated low-dimensional … WebbComplex seismic trace attributes were introduced around 1970 as useful displays to help interpret seismic data in a qualitative way. Balch of Marathon published the first article in the 1971 issue of Geophysics under the title of “Color Sonograms”.
