DESCRIPTION:Partition functions of vertex models with domain-wall boundarie
s have appeared in a variety of contexts ranging from enumerative combinato
rics to the study of gauge theories. The six-vertex model is the prototype
model where such boundary conditions were adopted and\, in that case\, the
model's partition function admits a compact representation in terms of a si
ngle determinant. Such representation has led to a number of developments i
n the field but seemed to be restricted to the six-vertex model. The next n
atural candidate for this study is the elliptic gl2 Solid-on-Solid (SoS) mo
del but\, despite all efforts\, the results suggested single determinantal
representations did not exist. This problem has only been recently solved w
ith the help of special functional equations originating from the dynamical
version of the Yang-Baxter algebra. In this talk I will discuss this probl
em and show how families of single determinantal representations for the el
liptic SoS model's partition function can be derived in a constructive mann
er.
