Abstract

For each pair of non-zero real numbers q 1 and q 2, Laustsen and Silvestrov have constructed a unital Banach *-algebra $${\fancyscript{C}_{q_1,q_2}}$$ which contains a universal normalized solution to the *-algebraic (q 1, q 2)-deformed Heisenberg–Lie commutation relations. We show that for (q 1, q 2) = (−1, 1), this Banach *-algebra is very proper; that is, if $${M\in\mathbb{N}}$$ and $${a_1, \ldots, a_M}$$ are elements of $${\fancyscript{C}_{-1,1}}$$ such that $${\sum_{m=1}^M a_m^*a_m=0}$$ , then necessarily $${a_1=a_2=\cdots=a_M=0}$$ .
