Publishing alone may be counterproductive?

According to my experience (50 years in academia) it works in just the opposite way. A PhD whose all papers are joint with her adviser raises a suspicion that she cannot work independently. It is good …

Questions about some parallel between polynomial and differential equation

The answer to Q2 is provided by Differential algebra created by Joseph Fels Ritt. He studied differential-algebraic varieties by analogy with algebraic ones. See Ritt, Joseph Fels, Differential algebr …

Good "casual" advanced math books

What's one person's "higher level topics" is another person's "elementary math", so you should be more specific about the desired level. But still you may try these books: Michio Kuga, Galois' dream, …

Is spherical trigonometry a dead research area?

It is not. As a proof, I will mention three relatively recent papers where I am a co-author: M. Bonk and A. Eremenko, Covering properties of meromorphic functions, negative curvature and spherical geo …

Who says understanding physics helps mathematicians? (A reference request) [Take the word "w...

Perhaps it is correct that this opinion is "widely acknowledged" but it is not unanimous. Here I collected some statements of some prominent mathematicians related to this question. Some of those stat …

Theorems with many distinct proofs

"what is worth proving is worth proving again" (Attributed to N. Katz in D. Ruelle's paper, The nature of properly human mathematics.) You are asking for a very long list: most deep and important th …

How can a mathematician handle the pressure to discover something new?

I can share my own experience: similar considerations always disturbed me too. To deal with this, I always considered mathematics research as a hobby. From the very beginning I thought that my main jo …

History of Gauss theorems that say "it clearly follows that" but it did not clearly follow

This could be related to the "Gauss problem" on the limit distribution of remainders of partial fractions. Gauss found this distribution, and in a letter to Laplace, claimed that he proved it. The fir …
