A proof is given that if the lower triangular infinite matrix $T$ acts boundedly on $\ell^2$ and U is the unilateral shift, the sequence $(U^*)^nTU^n$ inherits from $T$ the following properties: posinormality, dominance, $M$-hyponormality, hyponormal

Hyponormal operators are necessarily posinormal, but they need not be coposinormal. Coposinormality can nevertheless sometimes be an aid in determining hyponormality. This idea is applied to coposinormal factorable matrices whose interrupter is diago

The range inclusion criterion for posinormality is studied in order to classify more examples of lower triangular factorable matrices as posinormal operators or not. Also, coposinormality is shown to be a hereditary property for lower triangular oper

Introduction Thyroid pathology is frequent in Mali, which is an endemic zone for goiter. But this pathology rarely occurs in children. The purpose of our study was to characterize this illness among children in Mali. Methods We report on patients age

First it is shown that the Nörlund matrix associated with the sequence of positive integers is a coposinormal operator on $\ell^2$. This fact then turns out to be useful for showing that this operator is also posinormal and hyponormal. In contrast w
