Smallest singular value bound for general deterministic shifts of real Ginibre matrices
Smallest singular value bound for general deterministic shifts of real Ginibre matrices
Let be an real Ginibre matrix, let be a deterministic matrix, let , and define the Hermitian imaginary part by
Write for the smallest singular value and let denote the trace of . General shifted real Ginibre smallest singular value conjecture. There exist constants such that
The conjecture extends the shifted case to arbitrary deterministic matrices; the source notes that its preceding theorem proves the special case up to a logarithmic correction. The source does not state a resolution beyond this partial result.
