Reciprocal Convex Costs for Ratio Matching: Functional-Equation Characterization and Decision Geometry

Jonathan Washburn, Amir Rahnamai Barghi

We study ratio-induced mismatch costs of the form $c (s, o) = J (ι_{S} (s) / ι_{O} (o))$ , built from positive scale maps $ι_{S} : S \to (0, \infty)$ and $ι_{O} : O \to (0, \infty)$ and a penalty $J:(0,\infty…

The Coercive Projection Theorem for Canonical Reciprocal Costs

Jonathan Washburn, Amir Rahnamai Barghi

We develop a finite-data framework for certifying \emph{zero-defect} (neutral) configurations of positive vectors under the canonical separable reciprocal cost. We show that this s…
