经典场论的一种新几何设置

A new geometric setting for classical field theories

M. de Leon, J. C. Marrero, D. Martin de Diego

摘要:

介绍了经典场论的一种新的几何设置。这种描述是强烈的灵感,在一个由于斯金纳和腊斯克奇异拉格朗日系统。对于一个奇异的场论的约束算法的发展,给出了一个最终的约束子流形,一个定义良好的动态存在。该算法的主要优点是自动包含了二阶条件。

英文摘要:

A new geometrical setting for classical field theories is introduced. This description is strongly inspired in the one due to Skinner and Rusk for singular lagrangians systems. For a singular field theory a constraint algorithm is developed that gives a final constraint submanifold where a well-defined dynamics exists. The main advantage of this algorithm is that the second order condition is automatically included.
