Well, of course we can, but then ω·ν is not a linear function, so we have left the world of forms.(我们希望把2-form定义为线性的)The trick is to define the product of ω and ν to be a 2-form. So as not to confuse this with the product just mentioned, we will use the sy...
4 Newton's law of universal gravitation is valid. A brief discussion of this law was given in Chap. 3 (pages 65-67), and a more detailed discussion is given in Chap. 9. These assumptions are difficult to test individually to great precision. The most precise tests, which relate to the...

Although sets are at the root of modern mathematics, by themselves they are only of formal and abstract interest. To make sets useful, it is necessary to introduce some structures on them. There are two general procedures for the implementation of such structures. These(two general procedures) ...
