Dr. Janet Rowley was internationally renowned for her studies of chromosome abnormalities in human leukemia and lymphoma. We adored her closer to home as a University of Chicago lifer and a treasured member of our great Hyde Park/Kenwood community. A woman of tremendous grace and beauty, she distinguished herself not only for her historic scientific discoveries but also with her sustained effor...

Shiner–Davison–Landsberg complexity revisited

Shiner, Davison and Landsberg have recently proposed a measure of complexity that has become the subject of an intense debate. We show that using the framework of the thermodynamic formalism, the properties and shortcomings of this measure—over-universality and a trivial implementation of the temperature dependence—can be interpreted and elucidated in a coherent way. Moreover, we show how the S...

Janet-Like Monomial Division

In this paper we introduce a new type of monomial division called Janet-like, since its properties are similar to those of Janet division. We show that the former division improves the latter one. This means that a Janet divisor is always a Janet-like divisor but the converse is generally not true. Though Janet-like division is not involutive, it preserves all algorithmic merits of Janet divisi...
