Baikov representations, intersection theory, and canonical Feynman integrals
The method of canonical differential equations is an important tool in the calculation of Feynman integrals in quantum field theories. It has been realized that the canonical bases are closely
A first look at the function space for planar two-loop six-particle Feynman integrals
Abstract Two-loop corrections to scattering amplitudes are crucial theoretical input for collider physics. Recent years have seen tremendous advances in computing Feynman integrals, scattering
Integral representation for three-loop banana graph
It has recently been shown that two-loop kite-type diagrams can be computed analytically in terms of iterated integrals with algebraic kernels. This result was obtained using a new integral
Master integrals for bipartite cuts of three-loop photon self energy
We calculate master integrals for bipartite cuts of the three-loop propagator QED diagrams. These master integrals determine the spectral density of the photon self energy. Our results are expressed
Conservative Dynamics of Binary Systems at Fourth Post-Minkowskian Order in the Large-Eccentricity Expansion.
We compute the conservative dynamics of nonspinning binaries at fourth post-Minkowskian order in the large-eccentricity limit, including both potential and radiation-reaction tail effects. This is

Current higher-order calculations heavily rely on publicly available tools. These are not necessarily computer programs, but it is anything that aids in different steps of calculations, e.g. also
Non-planar elliptic vertex
Abstract We consider the problem of obtaining higher order in regularization parameter ε analytical results for master integrals with elliptics. The two commonly employed methods are provided by the
Two-loop amplitude for mixed QCD-EW corrections to $gg \to Hg$
We report on the two-loop amplitude computation for the mixed QCD-electroweak corrections to the process gg → Hg, with exact dependence on the electroweak boson masses. This amplitude has been

The role of differential equations in the process of calculating Feynman integrals is shown. An example of a diagram is given, in the calculation of which the method of differential equations was
Massive two-loop heavy particle diagrams
We determine the master integrals for vertex and propagator diagrams that appear in effective field theories containing heavy fields. The integrals involve at least one heavy line, and the standard

TLDR
It is argued that a good choice of basis for (multi)loop integrals can lead to significant simplifications of the differential equations, and criteria for finding an optimal basis are proposed.
Normalized Fuchsian form on Riemann sphere and differential equations for multiloop integrals
We consider the question of reducibility of the differential system to normalized Fuchsian form on the Riemann sphere. The differential equations for the multiloop integrals in $\epsilon$-form

Multiple polylogarithms, cyclotomy and modular complexes
The multiple ζ-values were invented and studied by Euler [E] and then forgotten. They showed up again in such different subjects as quantum groups [Dr] (the Drinfeld associator), Zagier’s studies
