More on the quantum potential

A possible thermalization of Fisher information is suggested for certain situations.Comment: 3 pages, Late

On some toy quantum cosmology

Some connections of the quantum potential to gravitation are discussed

Remarks on photons and the aether

We expand upon some topics reviewed and sketched in a book to appear with more details, embellishments, and some new material of a speculative nature.Comment: 28 pages, Late

Remarks on Whitham and RG

We collect a number of facts and conjectures concerning Whitham theory and the renormalization group. Some explicit relations and problems are indicated in the context of N=2 susy Yang-Mills.Comment: Latex 37 pages. Some additional discussion, problems, and references are adde

Fluctuations, gravity, and the quantum potential

We show how the quantum potential arises in various ways and trace its connection to quantum fluctuations and Fisher information along with its realization in terms of Weyl curvature. It is a quantization factor for certain classical systems as well as an expression for quantum matter in gravity theories of Weyl-Dirac type. We extract theories and examples from the literature, providing connections and interpretations, and make a few new observations.Comment: 50 pages, Late

Uncertainty, trajectories, and duality

We show explicitly how uncertainty can arise in a trajectory representation. Then we show that the formal utilization of the WKB like hierarchy structure of dKdV in the description of (X,psi) duality does not encounter norm constraints.Comment: Latex, 8 page

Remarks on the Schrodinger equation

Various origins of linear and nonlinear Schrodinger equations are discussed in connection with diffusion, hydrodynamics, and fractal structure. The treatment is mainly expository, emphasizing the quantum potential, with a few new observations.Comment: 34 pages, Latex, references and comments adde

Gravity and the quantum potential

We review some material connecting gravity and the quantum potential and provide a few new observations.Comment: Latex, 30 pages, Remark adde

Fisher, Kaehler, Weyl and the quantum potential

Connections between Fisher information, Kaehler geometry of a quantum projective Hilbert space, and the Weyl-Ricci scalar curvature of a Riemannian flat spacetime with quantum matter are sketched.Comment: 17 pages, Late

Prepotentials and Riemann surfaces

We organize and review some material from various sources about prepotentials, Riemann surfaces and kernels, WDVV, and the renormalization group, provide some further connections and information, and indicate some directions and problems.Comment: Latex, 26 pages. Some typos are corrected and a number of improvements are adde
