Curves of infinite genus I Riemann--Roch theorem for small degree
Ilya Zakharevich
The most useful and interesting line bundles over algebraic curves of a very high genus have the ratio δof the degree to the genus close to half-integer values, usually δ\approx 0,…

Geometic vertex operators
Ilya Zakharevich
Vertex operators, being families of birational transformations of infinite-dimensional algebraic ``varieties'' M, act on appropriate line bundles on M. However, they act on (meromo…
