My Unexpected Career Journey Chapter 13

One day after the paper is checked, it is published to Arxiv.

After proving the foundation of singular cardinal numbers, the remaining four solutions to singular cardinal numbers are all built on this foundation, so the solution papers are very easy to write.

This is like building a building: laying the foundation is difficult, but building the floors is easy.

Only with a good foundation can a taller building be built.

The same is true for the proof of singular cardinal numbers. The basics are difficult, but the solution is simple, and it is naturally easy to write.
