Consistent histories and the ultrametric on infinite tensor products
Andrew Lesniewski
The consistent histories formulation of quantum mechanics assigns classical probabilities to sequences of coarse-grained events when the corresponding interference terms vanish. In…
A complete ultrametric on von Neumann's incomplete tensor products
Andrew Lesniewski
We revisit von Neumann's theory of infinite tensor products of Hilbert spaces. On the set of equivalence classes of -sequences, which labels the incomplete tensor products…
Ricci flow for the Bures--Helstrom qubit metric
Andrew Lesniewski
The Bures--Helstrom metric is the minimal monotone Riemannian metric on the state space of a qubit. With the quantum Fisher normalization used here, it identifies the Bloch ball wi…
Mortgage Burnout and Selection Effects in Heterogeneous Cox Hazard Models
Andrew Lesniewski
We study the aggregate hazard rate of a heterogeneous population whose individual event intensities are modeled as Cox (doubly stochastic) processes. In the deterministic hazard se…
