SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Indagationes Mathematicae is the journal for Mathematical Sciences of the Royal Dutch Mathematical Society. The journal aims at the publication of original mathematical research papers of high quality, preferably of interest to a large segment of the mathematics community. Although the journal aims at general mathematical subjects, there is some preference for articles with a focus on analysis in a broad sense, including areas like dynamical systems, differential geometry and stochastics. Papers can be submitted via the Elsevier Editorial System EES http://ees.elsevier.com/indag/. The journal welcomes the submission of review papers of high quality.
