In the knowledge race model with spillover effects and imperfect absorptive capacity $)=(a*G*e^{-\frac{G}{c}}$

a$.$ the number of equilibria depends only on $S=a*G*e^{-\frac{G}{c}}$

b$.$ there are always $3$ equilibria for a given level of $c$

C$.$ the number of equilibria depends on the intersection$($s$)$ of $S=a*G*e^{-\frac{G}{c}}$ with bar $(r{)}_A-$ bar $(r{)}_B$
