points X ⊂ R n {\displaystyle X\subset \mathbb {R} ^{n}} is often called unisolvent for a space W {\displaystyle W} if any element w ∈ W {\displaystyle w\in...

approximation in the L∞-norm Unisolvent point set — function from given function space is determined uniquely by values on such a set of points Stone–Weierstrass...

another set of nodes with slow growth (although not as slow as the Chebyshev nodes) and with the additional property of being a unisolvent point set. The...

points are the first known example (and up to now the only one) of a unisolvent point set (that is, the interpolating polynomial is unique) with minimal growth...

a very simple solution, for instance, when one has a set of unisolvent functions, meaning a set of ⁠ n {\displaystyle n} ⁠ functions such that evaluating...
