Global scale efficiency in data envelopment analysis

International Transactions in Operational Research, Volume 32, Issue 5, Page 2474-2496, September 2025.
Abstract In the realm of assessing scale efficiency (SE), it tends to be computed as a firm‐specific phenomenon rather than something associated with the whole shape of the frontier of the technology under evaluation. This circumstance may lead to inaccuracies in the conclusions drawn regarding the returns to scale (RTS) exhibited across the entire ...

Efficient property value estimation for single‐family homes in central Florida

International Transactions in Operational Research, Volume 32, Issue 5, Page 2952-2980, September 2025.
Abstract This paper proposes the use of a metafrontier efficiency analysis approach to estimate residential property values. The objective is to mitigate inefficiencies in these valuations, thereby enhancing tax revenue and fairness in tax burdens. Property features (such as acreage, living area, number of bedrooms, number of bathrooms, age, and pool ...

Analysis of density matrix embedding theory around the non‐interacting limit

Communications on Pure and Applied Mathematics, Volume 78, Issue 8, Page 1359-1410, August 2025.
Abstract This article provides the first mathematical analysis of the Density Matrix Embedding Theory (DMET) method. We prove that, under certain assumptions, (i) the exact ground‐state density matrix is a fixed‐point of the DMET map for non‐interacting systems, (ii) there exists a unique physical solution in the weakly‐interacting regime, and (iii ...

A Sharper Ramsey Theorem for Constrained Drawings

Journal of Graph Theory, Volume 109, Issue 4, Page 401-411, August 2025.
ABSTRACT Given a graph G and a collection C of subsets of R d indexed by the subsets of vertices of G, a constrained drawing of G is a drawing where each edge is drawn inside some set from C, in such a way that nonadjacent edges are drawn in sets with disjoint indices. In this paper we prove a Ramsey‐type result for such drawings.

Note on Hamiltonicity of Basis Graphs of Even Delta‐Matroids

Journal of Graph Theory, Volume 109, Issue 4, Page 446-453, August 2025.
ABSTRACT We show that the basis graph of an even delta‐matroid is Hamiltonian if it has more than two vertices. More strongly, we prove that for two distinct edges e and f sharing a common end, it has a Hamiltonian cycle using e and avoiding f unless it has at most two vertices or it is a cycle of length at most four.
