A Tour on Classical Theorems on Multisecant Lines of Projective Varieties and Problems

Abstract

This note is intended to introduce some interesting classical re- sults on multisecant lines of projective varieties, varieties swept out by mul- tisecants and open questions regarding them to mathematicians with modest background on algebraic geometry. In addition, such questions have been solved and understood by using modern projective techniques on vector bun-dles and by new results around them.
