The title is self explanatory, isn't it? I am working on an encyclopedy about mathematicians and in one of my references, I found the symbol ℵ, which looks like the letter N. Is it a Greek letter? If yes, what letter is it and is it equivalent to N? Thanks.

It looks like it is a Hebrew aleph.

Hebrew? Never knew any math notations written in Hebrew. If so, what does it represent?

My math knowledge is next no zero but maybe this Wiktionary entry will explain it to you. It says that it is the symbol for the cardinality of a well-orderable infinite set.

Thank you. I also don't really understand but oh well. Is aleph the Hebrew equivalent of Arabic alif? If so, it's kinda weird that a letter which looks like N is an equivalent of A.

Why? Capital lambda looks like an A, capital sigma looks like an E, capital eta looks like an H, capital rho looks like a P, small nu looks like a V, small eta looks like an N... why would similarities to other alphabets, especially other alphabets not used by the language in question, matter even remotely (even if they shared a common origin 2000 years in the past)? 6 persons have voted this message useful | |||

By the way, in less time than it took you to write this post, and definitely in less time than you had to wait to get a response, you could have answered the question with a web search. The top results on Google to Is ℵ a Greek Letter? tells you all about Aleph, the Hebrew Alphabet, and how Aleph is used in mathematics, no need to spend several minutes looking even.
Just a tip for when you want an answer sooner rather than later. 8 persons have voted this message useful | |||

To me it looks much more similar to X than N.
