f(R) is a type of modified gravity theory which generalizes Einstein's general relativity. f(R) gravity is actually a family of theories, each one defined by a different function, f, of the Ricci scalar, R. The simplest case is just the function being equal to the scalar; this is general relativity. As a consequence of … See more Derivation of field equations In metric f(R) gravity, one arrives at the field equations by varying the action with respect to the metric and not treating the connection The variation of the … See more As there are many potential forms of f(R) gravity, it is difficult to find generic tests. Additionally, since deviations away from General Relativity … See more Gogoi-Goswami gravity has the following form See more f(R) gravity as presented in the previous sections is a scalar modification of general relativity. More generally, we can have a See more In Palatini f(R) gravity, one treats the metric and connection independently and varies the action with respect to each of them separately. The … See more In metric-affine f(R) gravity, one generalizes things even further, treating both the metric and connection independently, and assuming the … See more Starobinsky gravity has the following form Starobinsky gravity provides a mechanism for the cosmic inflation, just after the Big Bang when $${\displaystyle R}$$ was still large. However, it is … See more WebIn this book, the fundamentals of magnetism are treated, starting at an introductory level. The origin of magnetic moments, the response to an applied magnetic field, and the various interactions giving rise to different types of magnetic ordering in solids are presented and many examples are given.
