Modified Newtonian Dynamics In Dimensionless Form
W. F. Kao
Modified Newtonian dynamics proposed that gravitational field needs modifications when the field strength is weaker than a critical value . This has been shown to be a goo…
Parameterization of the Equation of State and the expansion history of the very recent universe
W. F. Kao
Motivated by a nice result shown by E. Linder, a detailed discussion on the choice of the expansion parameters of the Maclaurin series for the equation of states of a perfect fluid…
A note on 4-dimensional traversable wormholes and energy conditions in higher dimensions
W. F. Kao, Chopin Soo
We show explicitly that traversable wormholes requiring exotic matter in 4-dimensions nevertheless have acceptable stress-tensors obeying reasonable energy conditions in higher dim…
Universal Formula for the Expectation Value of the Radial Operator under the Aharonov-Bohm Flux and the Coulomb Field
W. F. Kao, Y. M. Kao, D. H. Lin
A useful and universal formula for the expectation value of the radial operator in the presence of the Aharonov-Bohm flux and the Coulomb Field is established. We find that the exp…
Stability of the Anisotropic Brane Cosmology
Chiang-Mei Chen, W. F. Kao
The stability of the Bianchi type I anisotropic brane cosmology is analyzed in this paper. We also study the effect of the brane solution by comparing the models on the 3-brane and…
The Effect of the (2+1)-Dimensional Gravity in the Spiral Galaxy
W. F. Kao, R. -T. Yu
The slowly decreasing rotational velocity of the Milky Way suggests the existence of the dark matter. One finds that the effect of the dark matter in a galaxy can be described by a…
