Abstract: K-equivalence arises naturally from the non-uniqueness issue of birational minimal models in algebraic geometry. Due to its simplicity, it leads to deep connections among various different branches in geometry.

I start by reviewing numerical results which were based on various integration theories. Then I state the K-equivalence conjectures I raised in 2001 and recent progresses made on analytic continuations of quantum cohomology.

Finally I discuss a very recent geometric result on the existence of algebraic cycles which induce equivalence of Chow motives. It is based on the decomposition theorem of peverse sheaves and the geometry of arc spaces.
