报告摘要  Abstract

This talk will start from an expository introduction to the smooth knot concordance group. Then we will review knot Heegaard Floer theory and introduce the Upsilon invariant recently defined by Ozsvath, Stipsicz and Szabo. Finally, we will survey a few results on linear independence in the concordance group as applications.
