Gene Freudenburg

Gene Freudenburg is a Professor in the Department of Mathematics at Western Michigan University, specializing in commutative algebra and affine algebraic geometry. His research examines algebraic transformations of polynomial rings and affine spaces, with particular attention to group actions and invariant theory.

Research focuses on:

• Hilbert's Fourteenth Problem and non-finitely generated invariant rings
• Locally nilpotent derivations and their applications
• Geometric structures of affine varieties
• Automorphism groups of polynomial rings

He authored the comprehensive monograph Algebraic Theory of Locally Nilpotent Derivations (Springer-Verlag, 2006), which has become a standard reference in the field. His recent work extends fundamental results in the classification of algebraic varieties and their geometric properties.
