## BBF.RetrieveWPrimeLTs

Retrieve leading terms of polynomials of W'.

### Syntax

BBF.RetrieveWPrimeLTs():LIST BBF.RetrieveWPrimeLTs(Degree:INT):LIST

### Description

*Please note:* The function(s) explained on this page is/are using the *ApCoCoABBFServer*. You will have to start the ApCoCoABBFServer in order to use it/them.

The first function without parameter retrieves the leading terms of the polynomials of W' from the ApCoCoABBFServer. The second function with parameter `Degree` >= 0 retrieves the leading terms of degree `Degree` of the polynomials of W'.

@param

*Degree*Retrieve the leading terms of degree Degree from the polynomials of set W'.@return List of leading terms of polynomials of set W'.

#### Example

Use Z/(32003)[x, y, z],DegLex; I:=Ideal(-4*x^2 + 1, -4*y^2 - 1, 5*z^2); BBF.Init(I); BBF.Steps(10); -- After computation has finished: BBF.RetrieveWPrimeLTs(); Output: [x^3, x^2y, x^2z, xy^2, y^3, y^2z, xz^2, yz^2, z^3]

#### Example

Use Z/(32003)[x, y, z],DegLex; I:=Ideal(-4*x^2 + 1, -4*y^2 - 1, 5*z^2); BBF.Init(I); BBF.Steps(10); -- After computation has finished: BBF.RetrieveWPrimeLTs(2); Output: [ ]
