# What is this symbol called?

Not much to this question, just can't find the name.

I cannot find what this symbol is called, its like a n with a tail before it. It is something to do with eigenvectors in my context.

Purpose is I need to put it in LaTeX.

• It's the Greek eta. – Angina Seng Feb 2 '19 at 18:59
• The greek letter eta $\eta$. – MSobak Feb 2 '19 at 18:59
• In LaTeX it is given by \eta. FYI see here. – TheSimpliFire Feb 2 '19 at 19:01
• If you're looking for $\TeX$ commands for symbols, Detexify lets you draw and it will try to guess the symbol. – Arthur Feb 2 '19 at 19:01
• @Arthur this has been added to my favorites, so useful, thank you. – user640923 Feb 2 '19 at 19:04

I assume you are refering to

$$\large\eta$$

which is the greek letter "eta".

• That's the one thanks. – user640923 Feb 2 '19 at 19:01
• @HectorHaffenden Happy to help. In this case you could just accept the answer if you are satisfied :) – mrtaurho Feb 2 '19 at 19:02
• Have to wait 9 mins, I will accept when I am able to :) – user640923 Feb 2 '19 at 19:03
• @HectorHaffenden Okay. to add some more context: the letter "eta" $\eta$ aswell as the letter "lambda" $\lambda$ are commonly used to denote eigenvectors and eigenvalues respectively. – mrtaurho Feb 2 '19 at 19:05
• @HectorHaffenden No need for apologies. I didn't know it for myself for a long time and only heard stories that this could happen in connection with serial votings. However, I appreciate your compliment as you would determine my posts as valuable and you surely can upvote them; but maybe not all at once ;) – mrtaurho May 13 '19 at 10:12

Actually, in your post it is $$\hat{\eta}_A.$$ The greek letter is $$\eta$$.
