Stable pointed trees of projective spaces
Abstract : In this talk I will describe higher dimensional analogues
of the moduli spaces of stable pointed rational curves, introduced in
joint work with Chen and Gibney. The spaces we define parametrize
certain singular marked schemes which we refer to as stable pointed
trees of projective spaces, and is closely related to the
Fulton-MacPherson configuration spaces. I will give a survey of what
we know about this collection of spaces and their operadic structure,
and describe various open questions.
