Usage
symmetricKernel(L, n)
Parameter | Type | Description |
---|---|---|
L |
![]() |
A differential operator |
n | ![]() |
A positive integer |
Returns
symmetricKernel L returns a basis for, where
is the
symmetric power of
.
Remarks
Using symmetricKernel can be more efficient than computing the symmetric power and its kernel separately.
Example
We compute the rational kernel of the second symmetric power of
as follows:
1 --> L := D^7 - x*D + 1/2; 2 --> K := symmetricKernel(L, 2); 3 --> tex(K);
