Structural Lie
The Structural Lie tackles one of social science's most mysterious problems. How is it possible to derive statements about the grand structures of social life from their effects in the small movements of everyday life? Prominent sociologist Charles Lemert shows how Marx and Freud provide some answers to this question. Marx derived from the commodity his picture of the capitalist system, Freud diagnosed the character of psyches from the details of dreams, slips and jokes. This wonderfully readable and engaging book lays the foundation for a new social science in an age where a microchip can convey a world of information.
Lie's Structural Approach to PDE Systems
Author: Olle Stormark
language: en
Publisher: Cambridge University Press
Release Date: 2000-06-15
Here is a lucid and comprehensive introduction to the differential geometric study of partial differential equations (PDE). The first book to present substantial results on local solvability of general and nonlinear PDE systems without using power series techniques, it describes a general approach to PDE systems based on ideas developed by Lie, Cartan and Vessiot. The central theme is the exploitation of singular vector field systems and their first integrals. These considerations naturally lead to local Lie groups, Lie pseudogroups and the equivalence problem, all of which are covered in detail. This book will be a valuable resource for graduate students and researchers in partial differential equations, Lie groups and related fields.
Structure-preserving Integrators in Nonlinear Structural Dynamics and Flexible Multibody Dynamics
This book focuses on structure-preserving numerical methods for flexible multibody dynamics, including nonlinear elastodynamics and geometrically exact models for beams and shells. It also deals with the newly emerging class of variational integrators as well as Lie-group integrators. It discusses two alternative approaches to the discretization in space of nonlinear beams and shells. Firstly, geometrically exact formulations, which are typically used in the finite element community and, secondly, the absolute nodal coordinate formulation, which is popular in the multibody dynamics community. Concerning the discretization in time, the energy-momentum method and its energy-decaying variants are discussed. It also addresses a number of issues that have arisen in the wake of the structure-preserving discretization in space. Among them are the parameterization of finite rotations, the incorporation of algebraic constraints and the computer implementation of the various numerical methods. The practical application of structure-preserving methods is illustrated by a number of examples dealing with, among others, nonlinear beams and shells, large deformation problems, long-term simulations and coupled thermo-mechanical multibody systems. In addition it links novel time integration methods to frequently used methods in industrial multibody system simulation.
