​Past-Selection Filtrations (PSF)
An operator-algebraic framework for quantum measurement, records, and time
What is PSF?
Past-Selection Filtrations (PSF) is a framework for understanding quantum measurement and temporal asymmetry by treating “collapse” as conditioning on stable past records rather than a physical discontinuity. The approach is grounded in operator algebras and uses filtrations of von Neumann subalgebras to formalize how accessible histories narrow as records accumulate.
