Projected-limit conjecture for twisted q-characters

Fix i\frac{in I}, a\frac{inmathbb{C}^*, a Weyl group element w\frac{in W, and a monomial mm independent of kk. Let MkM_k be the Kirillov–Reshetikhin monomial specified in the source, and let χqw(L(Mkm))\chi_q^w(L(M_km)) be the ww-normalized qq-character. Define projected ww-normalized qq-characters by applying the projection that replaces Ai,aqn11A_{i,aq^n}^{1}{}^{1} by e17falphaie^{17falpha_i} for n<Rn<R and leaves it unchanged for n\frac{ge R. Projected-limit conjecture. The projected ww-normalized qq-characters converge as k+k\to+\infty, and their limits converge as RR\to-\infty.
