NOTES FOR STUDENTS
This book was written thinking to the students attending to scientific faculties, Engineering and Physics in particular. Instead of a single block, it could be considered as a collection of different works, all concerning the extension of cross product and curl in higher dimensions. Some parts are in English, some others in Italian: that is caused by the heterogeneity of the book, composed by texts written in different times and for different purposes.
For those who are in hurry, we suggest to read just the article "Cross product in N Dimensions" (5 pages).
The works here reported are also available on-line.
