Welcome to sparse-ir tutorial#

This online document provides comprehensive tutorials of the Python library sparse-ir library and Julia library SparseIR.jl.

For information on the whole sparse-ir ecosystem (including Rust, C-API, and Fortran bindings), please refer to the sparse-ir documentation.

The tutorials follow the notation defined on the notation and conventions page of the sparse-ir documentation. The basic theory is explained there as well: the intermediate representation, sparse sampling, the discrete Lehmann representation, and summation over the Matsubara axis.

Please free to make a contact with the authors of each tutorial page if you have any questions!
