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

It’s a small workshop because the participants are only Chenlu Huang and me, held in 24 Summer online. This workshop focus on several topics about geometry and topology.

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

• When do we have k-spectral bundles?link

• How to tell a fiber bundle is trivial?link

• Introduction to stratified vector bundleslink

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