DESCRIPTION:We show how the sharp constant for the L^2^-L^6^ a
djoint restriction estimate for the circle can be
obtained by combining a sharp estimate for a trili
near operator with signed kernel and modelled on d
ouble convolutions of measures supported on circle
s\, together with the positive semidefinitiveness
of the Laplacian matrix of some signed weighted gr
aphs associated to the discretization of the probl
em obtained by Fourier series decomposition.\n\n(j
