My Talks in Small workshop about several topics about geometry and topology, 24 summer

• Sheaf theory: Notes for gtm65 chII, it’s about presheaves/sheaves, resolution of sheaves, cohomology theory and Cech cohomology. It’s more detailed (so more friendly) than gtm65.

• When do we have k-spectral bundles?

• How to tell a fiber bundle is trivial?

• Introduction to stratified vector bundles

• Selected topics in algebraic geometry I talk about blow up, smoothness based on my note (the above link).
