Estimation to structured distances to singularity for matrix pencils with symmetry structures: A linear algebra-based approach

Anshul Prajapati, Punit Sharma

We study the structured distance to singularity for a given regular matrix pencil $A+sE$, where $(A,E)\in \mathbb{S}\subseteq ({\mathbb{C}}^{n,n}{)}^2$. This includes Hermitian, skew-He…
