This thesis is basically centred on ....
\begin{figure}[t]

\caption{The motion of fluid substances is described by nonlinear $PDE$s, the Navier-Stokes equations.}
\label{fig:FluidFlow_NavierStokeEquation}

Compilando ottengo 2 errori riguardanti la figura che 'puntano' al file main.lof

Gli errori sono:
1) ! Undefined control sequence
2) Missing number, treated as zero
La cosa viene iterata per ogni figura che inserisco.
