We develop efficient algorithms for determining the number of global cubic fields of given discriminant. They are based on earlier work of Hasse for cubic number fields. Our new ingredients allow to enlarge the range of computations considerably. For

SUMMARY There is evidence that magma chambers are not fed by a continuous flow, but in the form of discrete magma batches. The possibility is considered that the chamber is fed by a magma bubble ascending through the region underneath, driven by buoy

We present a parallel GCD algorithm for sparse multivariate polynomials with integer coefficients. The algorithm combines a Kronecker substitution with a Ben-Or/Tiwari sparse interpolation modulo a smooth prime to determine the support of the GCD. We

To contribute pedagogies that reimagine relationships in a more-than-human world I adopt a posthuman approach to map the content and expressions of imagination in a series of pedagogical events on ...

In this paper, investigating the nonassociative version of groupoids and inverse semigroups, we study the relationship between these two algebraic structures and show that it can not be one-to-one.

Crustal Magmatic System Evolution
Magmas readily react with their surroundings, which may be other magmas or solid rocks. Such reactions are important in the chemical and physical evolution of magmatic systems and the crust, for example, in inducing volcanic eruptions and in the form
