Algorithmization of the me-T method

The authors introduce an algorithm combining the minimal error and the C̆ebyšev technique (the T-method) for solving equations of the form Ax+b=0, where x, b are vectors. A is an n×n matrix. A computer program is included as part of the article. (MR0448833

A second example of non-Keller mapping

In the article the next nontrivial example of non-Keller mapping having two zeros at infinity is analyzed. The rare mapping of two complex variables having two zeros at infinity is considered. In the article it has been proved that if the Jacobian of the considered mapping is constant, then it is zero
