Abstract
En 中文
We consider models for inference made by observers which may have multiple copies, such as occur in some multiverse theories. A toy model in this field is the Sleeping Beauty (SB) problem. We establish a framework for describing these problems on a probability space satisfying Kolmogorov's axioms. This enables the main competing approaches to be compared precisely.
