چکیده
We construct an exact analytic solution to the Friedman equations with a stringy inspired scalar matter and show explicitly an absence of the “Big Rip” singularity. The notable feature of this model is a wrong sign of the kinetic term and a special polynomial form of the effective tachyon potential. The method developed in the fivedimensional brane-world scenario is used. We show that the solution is stable with respect to small fluctuations of the initial conditions and present corresponding phase portraits.

Exactly Solvable SFT Inspired Phantom Model
An exact solution to the Friedmann equations with a string inspired phantom scalar matter field is constructed and the absence of the “Big Rip” singularity is shown explicitly. The notable features of the concerned model are a ghost sign of the kinetic term and a special polynomial form of the effective tachyon potential. The constructed solution is stable with respect to small fluctuations of ...

متن کاملA biologically inspired model for describing the user behaviors in a Cultural Heritage environment
We present a biologically inspired mathematical model for describing the personalized interactions of users with cultural heritage objects. The main idea is to measure the interest of an artwork spectator by means of a model able to capture the context and the visitor behaviors. In the proposed approach, the user is assimilated to a computational neuron, and its interests are deduced by countin...
متن کاملConstrained fluctuation theories of rubber elasticity: General results and an exactly solvable model
We present a new model of rubber elasticity where linear forces act to constrain the fluctuations of the eigenmodes of the phantom model. The model allows us to treat the constrained junction and the tube model within the same, transparent formalism, does not require any further approximations, and is particularly suited for the analysis of simulation data for (strained) model polymer networks....
