Clifford's Theorem on Special Divisors
Turgay Akyar
ODTÜ, Turkey
Özet : It is very well known that for a non-special divisor D, the dimension of a linear system |D| on a smooth projective curve over C depends only on the degree of D. On the other hand, if D is special, we do not have such a dependence. After giving some facts about linear systems on curves we will see a classical theorem mainly concerning with the extremal behavior of the dimension r(D) of a complete special linear system |D|.
