Sharp Spectral Bounds for Symmetric Positive Definite Tensors via Multiple Algebraic Invariants
Hemant Sharma, Snigdhashree Nayak, Ankit Singh
We extend the trace--determinant framework of Nayak, Sharma, and Mishra~\cite{nayak2026} for bounding the H-eigenvalues of symmetric positive definite tensors. First, we replace th…
