Factorisation in Dedekind RingExplains the factorisation of ideals in a Dedekind ring using prime ideals and covers ramification index, residual fields, inertia degree, and properties of Dedekind rings.
Rings and IdealsExplores rings, domains, fields, and ideals, with a focus on constructions and properties.
Irreducible Algebraic SetsExplores irreducible algebraic sets and their unique decomposition into components, with a focus on prime ideals and plane subsets classification.
Group Algebra: Maschke's TheoremExplores Wedderburn's theorem, group algebras, and Maschke's theorem in the context of finite dimensional simple algebras and their endomorphisms.
Local Rings and ResiduesCovers the proof of theorem 4.2 on multiplicities and the special structure of local rings at a simple point of a plane.
