Hello, is it possible to define assumptions globally? This is my (simplified) problem: To calculate certain quantities I wrote some modules like cE[n_,0,s_]:=Module[{}, cE[n,0,s]= E[n-1,0,s] Integrate[W[x,s],{s,0,1}] ] (cE[0,0,s] is of course defined) Later I would like to use for example : [Module-Def] Now, W might be quite complicated, so Integrate might need assumptions. is there a better way than : WAssumptions={} cE[n_,0,s_]:=Module[{}, cE[n,0,s]= E[n-1,0,s] Integrate[W[x,s],{s,0,1},Assumptions->WAssumptions] ] : WAssumptions={a>0} W[x_,s_]= a ...; : cE[n] ?
