- La principal importancia del álgebra de Pauli es proporcionarnos un escalón para la teoría de los espacios espinores. Sin embargo, es útil detenerse en este punto para demostrar que el formalismo ya desarrollado nos proporciona un marco eficiente para aspectos limitados, pero importantes, de la electrodianmia clásica (CED).
- 3.2: El campo libre de Maxwell
- Nuestro enfoque de CED hasta ahora es inusual en la medida en que hemos definido, clasificado y transformado efectivamente el campo electromagnético en una pequeña región del espacio-tiempo sin haber utilizado las ecuaciones de Maxwell. Esto es, por supuesto, un indicio de la efectividad de nuestra definición del campo en términos de transformaciones activas de Lorentz.
