% fix nonnegative integers $m, s, l$ with l+s=m+1$, a strictly increasing 
% $x\in\RR^\ZZ$, and set $a,b:=\lim_{n\to\pm\infty}x_n$. Pick a 1-1
% $[\phi_i: i=0:m]:\RR^{m+1}\to B$, $B$ some Bs of functions on $(a .. b)$.
% Call $A:=(a_n\in\RR^{m+1}: n\in\ZZ)$ $r$-complete if $[a_n,\ldots,a_{n+r}]$
% is 1-1 for all $n$. An $A$-(minimal (elementary) )spline is any element in 
% the span of $(\omega_n: n\in\ZZ)$, with $\supp \omega_n=[x_{n-s} .. 
% x_{n+l}]$ and $[\omega_n(t): n\in\ZZ]A' = [\phi_i(t): i=0:m]$ forall 
% $t\not\in x$. The $\omega_n$ are called the main basis for this space. 
% Theorem: $A$-minimal splines exist iff $A$ is $m$-regular, meaning that
% $[a_n,\ldots,a_{n+m}]$ is 1-1 forall $n$.
% properties discussed: smoothness of the $\omega_n$.
