I'm trying to use Isabelle to do auto-prove. However, I got a problem of specifying formulas in Isabelle. For example, I have a formulas like this
Then, I define sets and use big_wedge and big_vee symbols in Isabelle as follows:
And the result is "Inner lexical error⌂ Failed to parse prop".
Could you explain what is wrong here, please?
Thank you very much.

Not all symbols shown in Isabelle/jEdit's Symbol tabs have a meaning. These are the symbols you can use in your code.
Based on the corresponding code for sums, I started the setup, but I did not finish it (in particular, the syntax
⋀t!=l. P tis not supported).The full setup is possible. But I am not certain that this is a good idea... You will need a lot of lemmas to make things work nicely and I am not certain the behaviour for infinite sets is the right one.
