Computing with Crystallographic Groups
Algorithms are presented for the computation with crystallographic groups of arbitrary dimension, in particular for the determination of the Wyckoff positions and maximal subgroups of a space group, and for the determination of all space group types for a given point group. These algorithms have been implemented in the computer algebra system GAP, and are made publically available. The capabili...
متن کاملf(R) Theories
Over the past decade, f(R) theories have been extensively studied as one of the simplest modifications to General Relativity. In this article we review various applications of f(R) theories to cosmology and gravity - such as inflation, dark energy, local gravity constraints, cosmological perturbations, and spherically symmetric solutions in weak and strong gravitational backgrounds. We present ...
متن کاملf(R) Quantum Cosmology
We have quantized a flat cosmological model in the context of the metric f(R) models, using the causal Bohmian quantum theory. The equations are solved and then we have obtained how the quantum corrections influence the classical equations.

1. Laertes is about to stab Hamlet. Claudius, watching from the wings, desperately wants Laertes to stab Hamlet and has implanted a device in Laertes’ brain that, if activated, will force him to stab Hamlet. Claudius intends to activate the device if it appears that Laertes will change his mind at the last moment. Laertes, however, stabs Hamlet of his own accord and Claudius’s device is never a...
متن کاملCoordinate transformations in modern crystallographic computing.
A review of 4 x 4-matrix notation and of tensor formalism focused on crystallographic applications is presented. A discussion of examples shows how this notation simplifies tasks encountered in crystallographic computing.
