- Should pure math questions be on topic? 8 answers
I am learning quantum information/computation, and while reading my textbook, naturally some questions arise. Whenever I am stuck on an exercise or have a doubt I post my question on physics stack exchange. But most of my doubts are purely mathematical and, consequently, I am asked to migrate the question on [math.se]. But most of my doubts, although being mathematical in nature, are formulated in terms of Dirac (braket) notation and thus, when I post the question on math I am often asked to migrate it to physics stack exchange as it involves braket notation. Where should such questions be posted, which are purely mathematical but involve some physics notation?
