About this paper
Fulvio Gesmundo
Fulvio Gesmundo of Texas A&M University performed a detailed geometric analysis of the Iterated Matrix Multiplication (IMM) polynomial within the Algebraic Complexity Theory program. The study precisely characterized IMM_n,q's symmetry group and showed its dual variety is a hypersurface, ruling out dual degeneracy for this key polynomial, while also providing structural insights into its singular and higher-order Jacobian loci through quiver representation theory.
Key insights
- The Iterated Matrix Multiplication (IMM) polynomial is uniquely characterized by its connected symmetry group, making it a canonical object for study within GCT.
- The dual variety of the IMM hypersurface is itself a hypersurface, indicating that IMM does not exhibit dual degeneracy, unlike other polynomials for which this property has aided lower bound proofs.
- The singular locus of IMM_n,q can be precisely described as the variety of (n-1)-nilpotent representations of an equioriented quiver, providing a framework for its decomposition and dimension analysis.
