Everett's Relative-State Formulation of Quantum Mechanics Describes Everett's attempt to solve the measurement problem by dropping the collapse dynamics from the standard von Neumann-Dirac theory of quantum mechanics. From the Stanford Encyclopedia.
Mangled Worlds Quantum Mechanics Describes a variation on the many worlds interpretation in which the Born probability rule can be derived via finite world counting.
Many-Worlds FAQ This FAQ shows how quantum paradoxes are resolved by the "many-worlds" interpretation or metatheory of quantum mechanics. This FAQ does not seek to prove that the many-worlds interpretation is the "correct" quantum metatheor
Relational Quantum Mechanics An interpretation of quantum theory which discards the notions of absolute state of a system, absolute value of its physical quantities, or absolute event; from the Stanford Encyclopedia of Philosophy by Federico Laudisa and Carlo Rovelli.
