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

The sigma-model representation for p-branes ansatz and exact solutions in the model are given (e.g. solutions depending on harmonic function, spherically symmetric ones and black holes).

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.
