      abstract     = {Constraints on the Higgs boson self-coupling are set by
                      combining double-Higgs boson analyses in the
                      $b\bar{b}b\bar{b}$, $b\bar{b}\tau^+\tau^-$ and $b\bar{b}
                      \gamma \gamma$ decay channels with single-Higgs boson
                      analyses targeting the $\gamma \gamma$, $ZZ^*$, $WW^*$,
                      $\tau^+ \tau^-$ and $b\bar{b}$ decay channels. The data used
                      in these analyses were recorded by the ATLAS detector at the
                      LHC in proton$-$proton collisions at $\sqrt{s}=13$ TeV and
                      correspond to an integrated luminosity of 126$-$139
                      fb$^{-1}$. The combination of the double-Higgs analyses sets
                      an upper limit of $\mu_{HH} < 2.4$ at 95\% confidence level
                      on the double-Higgs production cross-section normalised to
                      its Standard Model prediction. Combining the single-Higgs
                      and double-Higgs analyses, with the assumption that new
                      physics affects only the Higgs boson self-coupling
                      ($\lambda_{HHH}$), values outside the interval $-0.4<
                      \kappa_{\lambda}=(\lambda_{HHH}/\lambda_{HHH}^{\textrm{SM}})<
                      6.3$ are excluded at 95\% confidence level. The combined
                      single-Higgs and double-Higgs analyses provide results with
                      fewer assumptions, by adding in the fit more coupling
                      modifiers introduced to account for the Higgs boson
                      interactions with the other Standard Model particles.},
