Veronese Varieties and Modules of Algebraic Forms,can be used to establish a number of algebro-differential properties in the large. This fact we shall here demonstrate with particular reference to the . varieties, and to the question of representing an algebraic form as a linear combination of other forms.狗窝 发表于 2025-3-24 03:53:38
Linear Partial Differential Equations,set of algebraic varieties, considered in Part Seven and, occasionally, in Parts Five and Six. This arises essentially from the fact that there exists an isomorphism between the commutative ring of linear differential operators with constant coefficients and the ring of polynominals in a finite number of indeterminates.innate 发表于 2025-3-24 07:22:23

Local Properties of Analytic Transformations at their United Points,ve rise. Some of the properties we shall be able to transfer, without difficulty, to the case of the local study of the united points of differentiable transformations of a differentiable variety into itself ; but we shall not dwell on this at present.Apoptosis 发表于 2025-3-24 23:02:28
