The pseudozero set of a system f of polynomials in n complex variables is the subset of Cn which is the union of the zero-sets of all polynomial systems g that are near to f in a suitable sense. This ...

The theory of Appell polynomials has long intrigued researchers due to its elegant algebraic structure and rich connections with differential equations. At its core, an Appell sequence is ...

We present a prognostic model for metastatic renal cell carcinoma based on fractional polynomials. We retrospectively analysed 425 metastatic renal cell carcinoma patients treated with subcutaneous ...
