Abstract: 'Simplicial affine buildings are used to study algebraic groups over fields with Z-valued valuation. For Λ a totally ordered abelian group, Λ-buildings are used to study algebraic groups over fields with Λ-valued valuation. This makes it natural to ask if simplicial affine buildings can be understood as Z-buildings, and whether and how it is possible to establish a category equivalence like correspondence between simplicial buildings and Z-buildings. The talk will sketch an answer to the first question and provide some insights and partial results into the second.'
