Portal

MaRDI Portal is a FAIR gateway to find and access mathematical research data

Welcome to the MaRDI Portal of the NFDI. This page is still in an early stage of development.

Search

You can query the mathematical research data knowledge graph here: Search (early beta!)

• Currently supported data sources: DLMF, CRAN, PolyDB, swMATH (partially), zbMATH (partially)

Example queries

• DLMF formulae
  • that contain sine and tangent functions
  • that depend indirectly on the gamma function
• swMATH software
• Examples through our Scholia extension:
  • Explore a topic, here: Ricci curvature
  • Explore an organisation, here: European Mathematical Society
  • Explore a researcher, here: Fan Chung
  • Explore a paper, here: Kaplan and Meier, 1958 — Nonparametric Estimation from Incomplete Observations

Under development

• Upcoming data sources: zbMATH Open
• Upcoming features (MaRDI roadmap):
  • Formula search
  • MaRDI-flavored Scholia
