Title: Binuclear interval order for the Kronecker algebra

Abstract: The binuclear interval order on the set of wide intervals in the lattice of torsion classes was introduced by E. Hanson, who showed that is defines a lattice structure if the algebra is $\tau$-tilting finite. We present a proof that this order is a lattice for the Kronecker algebra making use of connections between wide intervals and closed rigid sets of the reduced Ziegler spectrum of its derived category established by L. Angeleri, R. Laking and F. Sentieri.
