• Equivalent Definitions of Very Strict CD(K,N) -spaces 

  Schultz, Timo (Springer, 2023)

  We show the equivalence of the definitions of very strict CD(K,N) -condition defined, on one hand, using (only) the entropy functionals, and on the other, the full displacement convexity class DCN. In particular, we show ...

• Marketing communication metrics for social media 

  Töllinen, Aarne; Karjaluoto, Heikki (Inderscience Publishers, 2011)

  The objective of this paper is to develop a conceptual framework for measuring the effectiveness of social media marketing communications. Specifically, we study whether the existing marketing communications performance ...

• Serendipity in recommender systems 

  Kotkov, Denis (University of Jyväskylä, 2018)

  The number of goods and services (such as accommodation or music streaming) offered by e-commerce websites does not allow users to examine all the available options in a reasonable amount of time. Recommender systems are ...

• Tangent Lines and Lipschitz Differentiability Spaces 

  Cavalletti, Fabio; Rajala, Tapio (De Gruyter Open, 2016)

  We study the existence of tangent lines, i.e. subsets of the tangent space isometric to the real line, in tangent spaces of metric spaces. We rst revisit the almost everywhere metric di erentiability of Lipschitz continuous ...

• Tensorization of quasi-Hilbertian Sobolev spaces 

  Eriksson-Bique, Sylvester; Rajala, Tapio; Soultanis, Elefterios (EMS Press, 2024)

  The tensorization problem for Sobolev spaces asks for a characterization of how the Sobolev space on a product metric measure space X Y can be determined from its factors. We show that two natural descriptions of the Sobolev ...
