💡 Contrast with Kummer theory: In Kummer theory (characteristic 0 or coprime to n), the multiplicative group K^*/(K^*)ⁿ classifies abelian extensions. In Artin-Schreier-Witt theory (characteristic p), the additive structure of Witt vectors plays this role. The shift from multiplicative to additive is the fundamental difference. 🔗 magicinternetmath.com 🏴‍☠️ Subscribe to the Pioneers Club ⚡ fundamentals@zeuspay.com #bitcoin #education
