Abstract

The analysis of objects living on ultrametric trees, in particular the block-diagonalization of 4-replica matrices Mαβ;γδM^{\alpha \beta ; \gamma \delta}, is shown to be dramatically simplified through the introduction of properly chosen operations on those objects. These are the Replica Fourier Transforms on ultrametric trees. Those transformations are defined and used in the present work.
