Quantum Maslov classes

We give a construction of ``quantum Maslov characteristic classes'', generalizing to higher dimensional cycles the Hu-Lalonde-Seidel morphism. We also state a conjecture extending this to an $A _{\infty}$ functor from the exact path category of the space of monotone Lagrangian branes to the Fukaya category. Quantum Maslov classes are used here for the study of Hofer geometry of Lagrangian equators in $S ^{2}$, giving a rigidity phenomenon for the Hofer metric 2-systole, which stands in contrast to the flexibility phenomenon of the closely related Hofer metric girth studied by Rauch ~\cite{cite_Itamar}, in the same context of Lagrangian equators of $S ^{2}$. More applications appear in ~\cite{cite_SavelyevGlobalFukayacategoryII}.
