Abstract
The q-Onsager algebra \(O_q\) is presented by two generators \(W_0\), \(W_1\) and two relations, called the q-Dolan/Grady relations. Recently Baseilhac and Koizumi introduced a current algebra \({\mathcal {A}}_q\) for \(O_q\). Soon afterwards, Baseilhac and Shigechi gave a presentation of \({\mathcal {A}}_q\) by generators and relations. We show that these generators give a PBW basis for \({\mathcal {A}}_q\). Using this PBW basis, we show that the algebra \({\mathcal {A}}_q\) is isomorphic to \(O_q \otimes {\mathbb {F}} [z_1, z_2, \ldots ]\), where \({\mathbb {F}}\) is the ground field and \(\lbrace z_n \rbrace _{n=1}^\infty \) are mutually commuting indeterminates. Recall the positive part \(U^+_q\) of the quantized enveloping algebra \(U_q(\widehat{{\mathfrak {s}}{\mathfrak {l}}}_2)\). Our results show that \(O_q\) is related to \({\mathcal {A}}_q\) in the same way that \(U^+_q\) is related to the alternating central extension of \(U^+_q\). For this reason, we propose to call \({\mathcal {A}}_q\) the alternating central extension of \(O_q\).

Appendices
Appendix A
In this appendix we list some relations that hold in \({\mathcal {A}}_q\). We will define an algebra \({\mathcal {A}}^\vee _q\) that is a homomorphic preimage of \({\mathcal {A}}_q\). All the results in this appendix are about \({\mathcal {A}}^\vee _q\).
Define the algebra \({\mathcal {A}}^\vee _q\) by generators
and the following relations. For \(k \in {\mathbb {N}}\),
Recall that \(\rho =-(q^2-q^{-2})^2\), and define \({\mathcal {G}}_0\), \({\tilde{\mathcal {G}}}_0\) as in (14).
The algebra \({\mathcal {A}}^\vee _q\) has an automorphism \(\sigma \) and an antiautomorphism \(\dagger \) that satisfy Lemmas 3.1–3.3. For \({\mathcal {A}}^\vee _q\) we define the generating functions \({\mathcal {W}}^+(t)\), \({\mathcal {W}}^-(t)\), \({\mathcal {G}}(t)\), \({\tilde{\mathcal {G}}}(t)\) as in Definition 3.4. In terms of these generating functions the relations (60)–(63) look as follows:
Let s denote an indeterminate that commutes with t. Define the generating functions
and also
One checks that
For \({\mathcal {A}}^\vee _q\) the maps \(\sigma \), \(\dagger \) act on \(A(s,t), B(s,t), \ldots , S(s,t)\) as follow:
u | A(s, t) | B(s, t) | C(s, t) | D(s, t) | E(s, t) | F(s, t) |
---|---|---|---|---|---|---|
\(\sigma (u)\) | B(s, t) | A(s, t) | C(s, t) | G(s, t) | F(s, t) | E(s, t) |
\(\dagger (u)\) | \(-A(s,t)\) | \(-B(s,t)\) | \(-C(s,t)\) | \(-E(s,t)\) | \(-D(s,t)\) | \(-G(s,t)\) |
u | G(s, t) | H(s, t) | I(s, t) | J(s, t) | K(s, t) | L(s, t) |
---|---|---|---|---|---|---|
\(\sigma (u)\) | D(s, t) | I(s, t) | H(s, t) | J(s, t) | N(s, t) | M(s, t) |
\(\dagger (u)\) | \(-F(s,t)\) | \(-I(s,t)\) | \(-H(s,t)\) | \(-J(s,t)\) | \(-M(s,t)\) | \(-N(s,t)\) |
u | M(s, t) | N(s, t) | P(s, t) | Q(s, t) | R(s, t) | S(s, t) |
---|---|---|---|---|---|---|
\(\sigma (u)\) | L(s, t) | K(s, t) | Q(s, t) | P(s, t) | S(s, t) | R(s, t) |
\(\dagger (u)\) | \(-K(s,t)\) | \(-L(s,t)\) | \(-Q(s,t)\) | \(-P(s,t)\) | \(-R(s,t)\) | \(-S(s,t)\) |
By (64)–(67) the following relations hold in \({\mathcal {A}}^\vee _q\):
and also
For the previous 18 equations we apply \(\sigma \) to each side, and obtain the following relations that hold in \({\mathcal {A}}^\vee _q\):
and also

Appendix C
In this appendix we give some details from the proof of Theorem 6.1. In that proof we invoke the Bergman diamond lemma. In our discussion of that lemma we list the overlap ambiguities; there are four types (i)–(iv). Our goal in this appendix is to show that all the overlap ambiguities are resolvable. Our strategy is to express the overlap ambiguities in terms of generating functions that involve mutually commuting indeterminates r, s, t. There are four overlap ambiguities of type (i). Here is the first one. Using the GF reduction rules, let us evaluate the overlap ambiguity
We can proceed in two ways. If we evaluate \({\mathcal {W}}^+(t) {\mathcal {W}}^-(s)\) first, then we find that (72) is equal to a weighted sum with the following terms and coefficients:
Term | Coefficient |

\({\mathcal {G}}(s) {\mathcal {G}}(t) {\tilde{\mathcal {G}}}(r)\) | \(-a'_{r, t}b'_{t, s}e_{t, r} - a'_{r, t}B'_{t, s}e_{s, r} + A'_{r, t}b'_{r, s}e_{r, t}\) |

\({\mathcal {G}}(t) {\mathcal {W}}^+(r) {\mathcal {W}}^+(s) \) | \(-e_{t, s}F_{s, r} + A_{r, t}B'_{t, s}\) |

The overlap ambiguity (81) is resolvable.
We have shown that the overlap ambiguities of type (ii) are resolvable.
The overlap ambiguities of type (iii) are obtained from the overlap ambiguities of type (ii) by applying the antiautomorphism \(\dagger \) or \(\sigma \dagger \). Consequently they are resolvable.
It is transparent that the overlap ambiguities of type (iv) are resolvable.
We have shown that all the overlap ambiguities are resolvable.
