Reduction and a Concentration-Compactness Principle for Energy-Casimir Functionals
Energy-Casimir functionals are a useful tool for the construction of steady states and the analysis of their nonlinear stability properties for a variety of conservative systems in mathematical physics. Recently, Y. Guo and the author employed them to construct stable steady states for the Vlasov-Poisson system in stellar dynamics, where the energy-Casimir functionals act on number density func...
متن کاملFluidization from Continuous Outgassing as a Cause of Geological Structures
Several notable features were found on the surface the asteroid, probably the most interesting being the ponded craters that were discovered in the equatorial regions. These ponded craters appear to be impact craters that were subsequently partially filled with fine grained regolith. The ponded regolith is much younger than the crater itself, implying an impact-independent process for pond crea...
متن کاملThe Equivalence Principle as a Symmetry
It is shown that the extra coordinate of 5D induced-matter and membrane theory is related in certain gauges to the inertial rest mass of a test particle. This implies that the Weak Equivalence Principle is a geometric symmetry, valid only in the limit in which the test mass is negligible compared to the source mass. Exact solutions illustrate this, and show the way to possible resolutions of th...
متن کاملSpecies Inegalitarianism as a Matter of Principle
Most critics of species egalitarianism point to its counter-intuitive implications in particular cases. But this argumentative strategy is vulnerable to the response that our intuitions should give way in the face of arguments showing that species egalitarianism is required by our deepest, most fundamental moral principles. In this article, I develop an argument against deontological versions o...
متن کاملUnivalence as a Principle of Logic
It is sometimes convenient or useful in mathematics to treat isomorphic structures as the same. The recently proposed Univalence Axiom for the foundations of mathematics elevates this idea to a foundational principle in the setting of Homotopy Type Theory. It states, roughly, that isomorphic structures can be identified. We explore the motivations and consequences, both mathematical and philoso...
