DESCRIPTION:We uncover the field-theoretical origin of symmetr
y relations for multifractal spectra at Anderson\n
transitions and at critical points of other disord
ered systems. We show that such relations follow f
rom the\nconformal invariance of the critical theo
ry\, which implies their general character.We also
demonstrate that\nfor the Anderson localization p
roblem the entire probability distribution for the
local density of states\npossesses a symmetry ari
sing from the invariance of correlation functions
of the underlying nonlinear \nmodel with respect
to the Weyl group of the target space of the model
