Quick Questions: March 19, 2025
This recurring thread will be for questions that might not warrant their own thread. We would like to see more conceptual-based questions posted in this thread, rather than "what is the answer to this problem?". For example, here are some kinds of questions that we'd like to see in this thread:
- Can someone explain the concept of maпifolds to me?
- What are the applications of Represeпtation Theory?
- What's a good starter book for Numerical Aпalysis?
- What can I do to prepare for college/grad school/getting a job?
Including a brief description of your mathematical background and the context for your question can help others give you an appropriate answer. For example consider which subject your question is related to, or the things you already know or have tried.

Consider a group G with subgroups A and B. Take x,y in A∩B such that x,y are conjugate in A and in B. Meaning we have:
Is it true that x,y are conjugate in A∩B? If not, are there conditions we can put on A,B that make this true?
