Quot-Stack Moduli and Transverse Deformations of Graded Metabelian Lie Algebras
Marcel Blattner
We identify the graded metabelian locus inside the deformation theory of positively graded Lie algebras. Let be the free metabelian Lie algebra on and . For…
Tangential Action Spaces: Geometry, Memory and Cost in Holonomic and Nonholonomic Agents
Marcel Blattner
Living systems balance energetic efficiency with the capacity for path-dependent effects. We introduce Tangential Action Spaces (TAS), a geometric framework that models embodied ag…
Continuous-Time Quantum Walks on Directed Bipartite Graphs
Beat Tödtli, Monika Laner, Jouri Semenov +3
This paper investigates continuous-time quantum walks on directed bipartite graphs based on a graph's adjacency matrix. We prove that on bipartite graphs, probability transport bet…
The Role of Trends in Evolving Networks
Osnat Mokryn, Marcel Blattner, Yuval Shavitt
Modeling complex networks has been the focus of much research for over a decade. Preferential attachment (PA) is considered a common explanation to the self organization of evolvin…
Preferential Attachment in Online Networks: Measurement and Explanations
Jérôme Kunegis, Marcel Blattner, Christine Moser
We perform an empirical study of the preferential attachment phenomenon in temporal networks and show that on the Web, networks follow a nonlinear preferential attachment model in…
Recommendation systems in the scope of opinion formation: a model
Marcel Blattner, Matus Medo
Aggregated data in real world recommender applications often feature fat-tailed distributions of the number of times individual items have been rated or favored. We propose a model…
