Talk:contragredient
Add topicAppearance
It is quite hard to define a word, which has no use in natural language i.e. a context, which defines the words just by itself - not a strictly rigid convention, which is the case of contragredient. The only feasible explanation of the word may be that the grid of numbers representing the mathematical object is adjusted to be "contra" both in it's content (the inverse) and also in it's order in the grid (the transpose).
