I'm wondering if there are examples of mathematical theorems, lemmas, equations or other mathematical statements that have been named after multiple authors of the same name?
For example if two people both called Hamilton would have worked on a topic and a theorem subsequently named after them was called Hamilton-Hamilton theorem or a Wong-Wong equation?
I was thinking that perhaps in some families (Bernoulli for example) or with other rather common names this could have occurred but I can't remember an instance where I ever came across this.
