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:
“There is a patent office at the seat of government of the universe, whose managers are as much interested in the dispersion of seeds as anybody at Washington can be, and their operations are infinitely more extensive and regular.”
—Henry David Thoreau (1817–1862)
“I don’t want to be graded on a curve.”
—Mary Carillo (b. 1957)
