Abstract
This is the first in a sequence of papers to develop the theory of levels in quantum K-theory and study its applications. Our main results in this paper are toric mirror theorems for permutation-equivariant quantum K-theory with level structure. In some of the simplest examples, we see the surprising appearance of Ramanujan's mock theta functions.

Comments
There was a gap in the previous proof of the mirror theorem using the wall-crossing approach. We rewrote Section 4 and prove the toric mirror theorems using the adelic characterization developed by Givental-Tonita; additional changes to Section 2.3 (properties of the level structure); typos fixed; some references added
