General Properties of Feedback Amplifiers,ns, and, MacDowell-Mansouri gauge theory of gravity are discussed. Three-dimensional dimensional reductions from the topological gravitational sector in four dimensions, enable to recuperate the 2+1 Chern-Simons gravity and the corresponding .-dual theory, from the notion of self-duality in the four

Alex Abramovici Ph.D.,Jake Chapsky P.E.pal fiber bundle structure and the toroidal dimensional reduction process in order to study what modifications are obtained to the standard Einstein-Maxwell-dilaton theories. We obtain an effective four dimensional gravity theory endowed with a cosmological term, a scalar dilaton field, an Einstein

Introduction to Feedback Economics, work together. We present the complete solution to the 95% scalar field cosmological model in which the dark matter is modeled by a scalar field . with the scalar potential . and the dark energy is modeled by a scalar field ., endowed with the scalar potential .. This model has only two free parame

The coupling function . is kept arbitrary and the self interacting potential is chosen to obtain exact solutions. Quantum wormholes and classical non-singular solutions are given.
