Unconditionality of general Franklin systems in L<sup>p</sup>[0,1], 1<p<โ
By a general Franklin system corresponding to a dense sequence ${\cal T}=(t_n, n \geq 0)$ of points in $[0,1]$ we mean a sequence of orthonormal piecewise linear functions with knots ${\cal T}$, that is, the $n$th function of the system has knots $t_0, \
