Hölder-Type Global Error Bounds for Non-degenerate Polynomial Systems

Si Tiep Dinh, Ha Huy Vui, Pham Tien Son

Let $F := (f_{1}, \dots, f_{p}) : R^{n} \to R^{p}$ be a polynomial map, and suppose that $S := {x \in R^{n} : f_{i} (x) \leq 0, i = 1, \dots, p} \neq = \emptyset.$ …

Horizontal gradient of polynomial functions for the standard Engel structure on $R^{4}$

Si Tiep Dinh, Krzysztof Kurdyka

We investigate the set $V_{f}$ of horizontal critical points of a polynomial function $f$ for the standard Engel structure defined by the 1-forms $ω_{3} = d x_{3} - x_{1} d x_{2},$ $ω_4=dx_4-x_3dx_…
