This study aims at developing multi-isotope tracer techniques, which consist of analyzing stable isotope ratios of light elements (carbon, nitrogen and others) from soft tissue (muscle or organs) and ...

We present and compare several algorithms for evaluating Jacquet's Whittaker functions for SL(3,ℤ). The most suitable algorithm is then applied to the problem of evaluating a Maass form for SL(3,ℤ) ...
