‘’雷格微积分‘’的方法被推广到电磁情况。为此，发展了一种“仿射”张量形式和相关的外部微积分。以二维标量波动方程为例，说明了线性场方程组的单纯形方法，并在此基础上讨论了连续统极限的变异性。
The ’’Regge calculus’’ approach is extended to the electromagnetic case. To this end an ’’affine’’ tensor formalism and associated exterior calculus are developed. The simplicial approach to linear field equations is illustrated by the two‐dimensional scalar wave equation, on which also a discussion of the treacherous character of the continuum limit is based.
