Product developing organizations rapidly increase their investments in digital platforms to capture value from external ecosystems. This enforces a shift in attention from up-front development of enduser functions to generic resources, providing design capability in those ecosystems. However, to cultivate a prosperous ecosystem around its platform firms also need to invest in building an initia...

We prove Manin’s conjecture for a split singular quartic del Pezzo surface with singularity type 2A1 and eight lines. This is achieved by equipping the surface with a conic bundle structure. To handle the sum over the family of conics, we prove a result of independent interest on a certain restricted divisor problem for four binary linear forms.

Combining different product types into standard discount bundles is a common strategy used by producers and wholesalers to increase overall sales profitability. While markets consist of many producers and retailers, a deal is typically made between a single producer and a single retailer. This paper deals with a producer who sells items separately, and considers setting and selling standard dis...

This paper presents a geometric description of Lagrangian and Hamiltonian systems on Lie affgebroids subject to affine nonholonomic constraints. We define the notion of nonholonomically constrained system, and characterize regularity conditions that guarantee that the dynamics of the system can be obtained as a suitable projection of the unconstrained dynamics. It is shown that one can define a...

For any number field k, upper bounds are established for the number of k-rational points of bounded height on non-singular del Pezzo surfaces defined over k, which are equipped with suitable conic bundle structures over k.

In this paper we take a close look at Lie derivatives on a Finsler bundle and give a geometric meaning to the vanishing of the mixed curvature of certain covariant derivatives on a Finsler bundle. As an application, we obtain some characterizations of Landsberg manifolds.

The Scholarship of Teaching and Learning promotes teaching as a scholarly endeavor and a worthy subject for research, producing a public body of knowledge open to critique and evaluation. Its intent is not only to improve teaching but to create a community of “scholarly teachers” who add to the body of knowledge about teaching and learning as well as benefiting from the SoTL research of others....

We consider judgment aggregation over multiple independent issues, where the chairperson has her own opinion, and can try to bias the outcome by bundling several issues together. Since for each bundle judges must give a uniform answer on all issues, different partitions of the issues may result in an outcome that significantly differs from the “true”, issue-wise, decision. We prove that the bun...
