One sided orthogonal polynomials and a pointwise convergence result for $SU(2)$-valued nonlinear Fourier series

Michel Alexis, Gevorg Mnatsakanyan, Christoph Thiele

We elaborate on a connection between the $SU(2)$-valued nonlinear Fourier series and sequences of left and right orthogonal polynomials for complex measures on the unit circle. We…
