- 81T13 should have something about sigma models; ALG suggests a separate
code however we've been putting things in 81T13 so it'd have to be 81T14; the 2-dim sources go in 81T40
- 81T75 has been taking both $q$-nc and NCG (Connes) traffic

81T28 Thermal quantum field theory
Many papers consider this field as a part of section 81Txx by its own, so it may be fair to introduce this classification with the link to 82B30.
81T55 Casimir effect
The Casimir effect as a fundamental topic of quantum field theory is investigated intensively at present. I suggest it to be accentuated by its own calssification.
The Casimir effect is under intensive investigation as a fundamental topic of quantum field theory recently. I think it is advantageous to introduce this item into the MSC.
