Direct recurrence conjecture. The coefficients can be computed directly by

Consider $d53d^n$ endowed with the metric $d(x,y)=\lVert x-y\rVert$, where the norm is any norm on $d53d^n$. Let $S_2$ be a subdivision scheme on $d53d^n$ satisfying, for…

Let $I=\{i:c_i>0\}$ be the support of the mask of a dyadic subdivision scheme with non-negative coefficients. Convergence conjecture. The subdivision scheme converges unless the gr…

Let $n\ge 2$ and let $\Lambda_n=\{\lambda_0,\ldots,\lambda_{n-1}\}$ be an arbitrary set of real numbers. Let $\psi^{\Lambda_n}$ be the generalized Daubechies wavelet associated wit…
