TARCER is an implementation of the recurrence algorithm of O.V. Tarasov for the reduction of two-loop propagator integrals with arbitrary masses to a small set of basis ...

Visualizations illustrate learning in an artificial neural network

The visualization of mathematical concepts is not a trivial cognitive activity: to visualize is not the same as to see. In our context, to visualize is the ability to create ...

An algorithm for solving nonlinear Heisenberg operator equations by extending the solution into series is presented. it is used for solving quantum nonlinear equations. The ...

The main points of the SOFISMA project [1] are presented. The project aim is to realize a package for the didactic of mathematics, with multi-level hypertexual organization ...

e^At is computed as the inverse Laplace transform of the resolvent kernel.

Calculators that can find the roots of characteristic polynomials have made many stability tests (Routh, Hurwitz, Sturm, etc) obsolete. Likewise, Bode plots have been ...
