演 題 : Vector bundles and algebraic-geometric codes
アブストラクト :
Algebraic-geometric(AG) codes is the error-correcting codes obtained
from algebraic varieties defined over a finite field. Starting from
Goppa’s original construction using divisors on algebraic curves,
almost all constructions of AG codes have been based on line bundles
on projective varieties. In this talk we would like to explain how one
can construct new types of AG codes using vector bundles of higher
rank.
