Abstract

We establish a local equivalence between toric steady K\"ahler-Ricci solitons and AA-type toric generalized K\"ahler-Ricci solitons (GKRS). Under natural global conditions we show this equivalence extends to complete GKRS, yielding a general construction of new examples in all dimensions. We show that in four dimensions, all GKRS are either described by the generalized K\"ahler Gibbons-Hawking ansatz, or have split tangent bundle, or are AA-type toric. This yields a local classification in four dimensions, together with a conjecturally exhaustive construction of complete symplectic-type examples.
