For an algebraic subvariety S subset of or equal to P-n, we present an explicit formula for the degree of the divisor of solutions of a differential equation on S and give some examples of applications. We extend the technique and result to the real case.engjournal articlehttp://www.tandfonline.com/doi/pdf/10.1080/00927870008827187http://www.tandfonline.com/restricted access512Divisor of solutions of a differential equationGrassmannians of a tangent bundleIntersection numbersSchubert cyclesDivisor of solutionsPlaneÁlgebra1201 Álgebra
