Odd-Weight Zeta Values from a Single Normalized Kernel via an Euler–Sum Operator

This is a preliminary preprint (work in progress).It presents a compact kernel–operator framework for isolating odd-weight Riemann zeta values from a single normalized rational kernel via an Euler–sum transformation.All analytic steps are classical; the contribution lies in the explicit conjugation-derived normalization and reusable operator workflow.Further numerical validation and extensions are in progress.Readers are encouraged to treat this version as exploratory and subject to revision in future updates.For feedback email [email protected]
