Thermal potential

$\omega (r)$ is the thermal potential, given by

$\omega (r)\equiv \gamma (r)B(r)$

where $\gamma (r)$ is the indirect correlation function, and Failed to parse (Conversion error. Server ("https://wikimedia.org/api/rest_") reported: "Cannot get mml. Server problem."): {\displaystyle B(r)} is the bridge function.
