✦ Synopsis

We shall present an introduction to the theory of gravity on locally anisotropic spaces modelled as vector bundles provided with compatible nonlinear and distinguished linear connection and metric structures (such spaces are obtained by a nonlinear connection reduction or compactification from higher dimensional spaces to lower dimensional ones and contain as particular cases various generalizations of Kaluza Klein and Finsler geometry). We shall analyze the conditions for consistent propagation of closed strings in locally anisotropic background spaces. The connection between conformal invariance, the vanishing of the renormalization group ;-function of the generalized _-model, and field equations of locally anisotropic gravity will be studied in detail.

## Abstract Infrared modifications of gravity have been proposed over the years as potentially useful phenomenological models. Massive (multi)‐gravity is an interesting class of such theories. The true nature and the ultimate consistency of many of these models remains, however, unclear as one is f

The kinetic theory is formulated with respect to anholonomic frames of reference on curved spacetimes. By using the concept of nonlinear connection we develop an approach to modelling locally anisotropic kinetic processes and, in corresponding limits, the relativistic nonequilibrium thermodynamics w
