Here we study the Brill-Noether theory of special linear systems on a singular Gorenstein bielliptic curve Y . Any such linear system is associated to a spanned rank 1 torsion-free sheaf, L. We obtain the same results as in the case of a smooth curve if either L โˆˆ Pic(Y ) or Y has only ordinary node

Phase singularities and coherence vortices in linear optical systems
โœ Greg Gbur; Taco D. Visser ๐Ÿ“‚ Article ๐Ÿ“… 2006 ๐Ÿ› Elsevier Science ๐ŸŒ English โš– 268 KB

It is demonstrated for a time-invariant linear optical system that there exists a definite connection between the optical vortices (phase singularities of the field amplitude) which appear when it is illuminated by spatially coherent light and the coherence vortices (phase singularities of the field
