A way of geometrically representing symmetric 2 × 2-gradients is proposed, and a general theorem characterizing sets of gradients is proved. We believe this perspective may help in understanding the structure of gradients and visualizing it. Several non-trivial examples are discussed.
Se propone una manera de representar geométricamente gradientes simétricos 2 x 2 y se prueba un teorema que caracteriza tales conjuntos de gradientes. Creemos que esta perspectiva puede ayudar a comprender la estructura de tales gradientes y visualizarla geométricamente. Se ilustran los resultados con varios ejemplos interesantes.
