Geometric Data Science develops geographicstyle maps and polynomialtime algorithms for moduli spaces of data objects considered modulo practically important equivalence relations.
The first solved case (based on papers in
FoCM 2024,
ACA 2023,
Chirality 2023)
is the space of 2dimensional lattices modulo rigid motion and uniform scaling, parametrised as a unit square whose vertices (0,0) and (0,1) represent all square and hexagonal lattices, resp. After identifying the boundary sides, this space becomes a 2D sphere whose equator represents all mirrorsymmetric 2D lattices.
Other major objects are unordered point clouds, e.g. clouds of atomic centres in a molecule, geometric graphs, e.g. molecular graphs in 3D and abstract graphs in metric spaces, and periodic point sets modelling solid crystalline materials, all considered under isometry (any distancepreserving transformation).
In the image: the benzene is represented by the hexagonal cloud of carbon atoms without hydrogens; the water molecule is represented by the graph with one oxygen and two hydrogens;
the table salt NaCl is represented by a cubic lattice of sodium and chlorine ions.

 The image shows the kite in the middle (in green and yellow) and the trapezium at the bottom (in red, yellow, and blue) whose sets of 4 vertices are indistinguishable by 6 pairwise distances. This pair motivated the new stronger invariants.
 Geometric Data Science is presented in the tutorials at
SIAM MDS (2 hours: slides),
FANeSy (1.5 hours), IMSI (1 hour), minisymposia at
the European Congress of Mathematics (2 hours), Mathematical Aspects of Materials Science (4 hours).

 Input: a radius r of two robots and a metric graph G with fixed lengths of edges.
 Output: connected components of the configuration space of two robots in G.
 Running time: O(n^{4}) for the number n of vertices in the given graph G.
 Abstract. A connected metric graph G with n vertices and without loops and multiple edges can be represented as an nbyn matrix whose entries are length of edges of G. A robot in the metric graph G is a metric ball with a centre x in G and a radius r>0. The configuration space OC(G,r) of two robots in G is the set of all centers (x,y) such that the centres x,y are at least 2r away from each other. We introduce the configuration skeleton CS(G,r) that captures all connectivity information of the space OC(G,r). As a consequence we get a polynomial time algorithm to find all connected components of OC(G,r) that are maximal subsets of all positions (x,y) connectable by collisionfree motions.
