The Most Mundane Example of A Two-point Tensor

The most mundane example of a two-point tensor is the transformation tensor, the Q in the above discussion. Note that

Now, writing out in full,

and also

This then requires Q to be of the form

.

By definition of tensor product,

So we can write

Thus

Incorporating (1), we have

Famous quotes containing the words the most and/or mundane:

    “We noticed several other sandy tracts in our voyage; and the course of the Merrimack can be traced from the nearest mountain by its yellow sand-banks, though the river itself is for the most part invisible. Lawsuits, as we hear, have in some cases grown out of these causes. Railroads have been made through certain irritable districts, breaking their sod, and so have set the sand to blowing, till it has converted fertile farms into deserts, and the company has had to pay the damages.”

    “Bourgeois existence is the regime of private affairs ... and the family is the rotten, dismal edifice in whose closets and crannies the most ignominious instincts are deposited. Mundane life proclaims the total subjugation of eroticism to privacy.”
    —Walter Benjamin (1892–1940)
