How to enter these symbols on a computer

Question

I am reading a book, and I need to recreate these symbols. So far, I have only gotten the first one(on MathType) and need the one that looks like a beta. How can I get these symbols in an editable form? Symbols

Answer 1

There are Fraktur A and P there.

$\mathfrak{A, P}$

In Tex/Latex you get these by using a command such as

\mathfrak{A, P}
