I'm a bit confused about why this QM question was migrated from PSE to this question on MSE. I believe the more appropriate forum for this specific mathematical-physics question is PSE. Could someone please shed some light on how the migration decisions are made and if question-authors' decisions for choosing a specific SE site to post questions are taken into account.
This question was migrated to Mathematics Stack Exchange (MSE) because it can be answered by people studying math at any level and professionals in related fields. Migrated 9 hours ago by Miyase, ZeroTheHero, Hyperon.
