Is correct to say that two vectors , three vectors or n vectors as a common point of origin form a tensor ? What is the correct geometric representation of a tensor ? The doubt arises from the fact that in books on the subject , in general there is no geometric representation. Sometimes appears a geometric representation as the following: a triad in 3 faces of a cube , indicating the presence of a stress tensor . But this representation does not clarify exactly what is the geometric representation of a tensor. Thank you for help!
