Abstract

We obtain results about fundamental groups of RCD* (K, N) spaces previously known under additional conditions such as smoothness or lower sectional curvature bounds. For fixed K is an element of R, N is an element of [1, infinity), D > 0, we show the following: center dot There is C > 0 such that for each RCD* (K, N) space X of diameter 0 such that for each RCD* (K, N) space X of diameter

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Journal Fur Die Reine Und Angewandte Mathematik due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2023, it was in position 80/490, thus managing to position itself as a Q1 (Primer Cuartil), in the category Mathematics.

From a relative perspective, and based on the normalized impact indicator calculated from the Field Citation Ratio (FCR) of the Dimensions source, it yields a value of: 5.11, which indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: Dimensions Aug 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-08-14, the following number of citations:

  • WoS: 1

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-08-14:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 6.

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.75.
  • The number of mentions on the social network X (formerly Twitter): 4 (Altmetric).
