Operations On Graded Vector Spaces
Some operations on vector spaces can be defined for graded vector spaces as well.
Given two I-graded vector spaces V and W, their direct sum has underlying vector space V ⊕ W with gradation
- (V ⊕ W)i = Vi ⊕ Wi .
If I is a semigroup, then the tensor product of two I-graded vector spaces V and W is another I-graded vector space, with gradation

Famous quotes containing the words operations, graded and/or spaces:
“It may seem strange that any road through such a wilderness should be passable, even in winter, when the snow is three or four feet deep, but at that season, wherever lumbering operations are actively carried on, teams are continually passing on the single track, and it becomes as smooth almost as a railway.”
—Henry David Thoreau (18171862)
“I dont want to be graded on a curve.”
—Mary Carillo (b. 1957)
“Though there were numerous vessels at this great distance in the horizon on every side, yet the vast spaces between them, like the spaces between the stars,far as they were distant from us, so were they from one another,nay, some were twice as far from each other as from us,impressed us with a sense of the immensity of the ocean, the unfruitful ocean, as it has been called, and we could see what proportion man and his works bear to the globe.”
—Henry David Thoreau (18171862)
