degreeOfJetSeparation -- computes the degree of jetSeparation at a given point

Usage:

degreeOfJetSeparation(A,pt)
Inputs:
- A, a matrix, or a list where the columns are lattice points
- pt, a matrix, a point as a column vector
Outputs:
- k, an integer, the maximal such that the embedding specified by A is k-jet spanned at pt

Description

degreeOfJetSeparation is a function. Given the set of lattice points of a convex polyhedron and a point a matrix it computes the maximal k such that the associated line bundle is k-jet spanned at the point

i1 : P=convexHull(matrix{{0,2}});

i2 : Q=convexHull(matrix{{0,4}});

i3 : A=latticePoints(cayley({P,Q},2));

i4 : pt=matrix{{1},{1}};

              2       1
o4 : Matrix ZZ  <-- ZZ

i5 : degreeOfJetSeparation(A,pt)

o5 = 2
