Given a $2$-commutative diagram
in a symmetric monoidal $(\infty ,2)$-category
$\mathscr{E}$ where
$X,Y\in \mathscr{E}$ are dualizable objects and
$\unicode[STIX]{x1D711}$ admits a right adjoint we construct a natural morphism
$\mathsf{Tr}_{\mathscr{E}}(F_{X})\xrightarrow[{}]{~~~~~}\mathsf{Tr}_{\mathscr{E}}(F_{Y})$ between the traces of
$F_{X}$ and
$F_{Y}$, respectively. We then apply this formalism to the case when
$\mathscr{E}$ is the
$(\infty ,2)$-category of
$k$-linear presentable categories which in combination of various calculations in the setting of derived algebraic geometry gives a categorical proof of the classical Atiyah–Bott formula (also known as the Holomorphic Lefschetz fixed point formula).
