Effectiveness of Article 102 of the Treaty on the Functioning of the European Union (TFEU) in regulating digital markets

2019

The effectiveness of Article 102 of the Treaty on the Functioning of the European Union (TFEU) in regulating digital markets is at doubt. Research has shown that due to advancement of digital markets and its specific characteristics, the impact on traditional standards is high, requiring modifications. This study aims to evaluate the effectiveness of EU competition law and demonstrate proposals to enforce the law more efficiently. By targeting the digitalization era, it asks: To what extent EU competition law, in particular Article 102 TFEU is effective in regulating digital markets? Based on a review of Article 102 TFEU, the European Commission’s decisions, the Commission’s Guidance, the C…

Homotopy limits for 2-categories

2008

AbstractWe study homotopy limits for 2-categories using the theory of Quillen model categories. In order to do so, we establish the existence of projective and injective model structures on diagram 2-categories. Using these results, we describe the homotopical behaviour not only of conical limits but also of weighted limits. Finally, pseudo-limits are related to homotopy limits.
