An analog of Leclerc's conjecture for bases of quantum cluster algebras
Dual canonical bases are expected to satisfy a certain (double) triangularity property by Leclerc's conjecture. We introduce an analogous conjecture for common triangular bases of quantum cluster algebras. We show that a weaker form of the analogous conjecture is true. Our result applies to the dual canonical bases of quantum unipotent subgroups. It also applies to the $t$-analogs of $q$-characters of simple modules of quantum affine algebras.
