Section 4.1.6 says:

inherited_olist(S,G,rpt) =
           ( joins(*,*,RP(G)) (+) joins(*,G) (-) prunes(S,G,rpt) )
       (+) ( pim_include(*,G) (-) pim_exclude(S,G))
       (-) ( lost_assert(*,G) (+) lost_assert(S,G,rpt) )

It should say:

inherited_olist(S,G,rpt) =
           ( ( ( joins(*,*,RP(G)) (+) joins(*,G) ) (-) prunes(S,G,rpt) )
       (+) ( pim_include(*,G) (-) pim_exclude(S,G)) )
       (-) ( lost_assert(*,G) (+) lost_assert(S,G,rpt) )
Or:
inherited_olist(S,G,rpt) =
           ( ( joins(*,*,RP(G)) (+) joins(*,G) ) (-) prunes(S,G,rpt) )
       (+) ( ( pim_include(*,G) (-) pim_exclude(S,G))
       (-) ( lost_assert(*,G) (+) lost_assert(S,G,rpt) ) )
Or:
inherited_olist(S,G,rpt) =
           ( ( joins(*,*,RP(G)) (+) ( joins(*,G) (-) prunes(S,G,rpt) ) )
       (+) ( pim_include(*,G) (-) pim_exclude(S,G)) )
       (-) ( lost_assert(*,G) (+) lost_assert(S,G,rpt) )
Or:
inherited_olist(S,G,rpt) =
           ( joins(*,*,RP(G)) (+) ( joins(*,G) (-) prunes(S,G,rpt) ) )
       (+) ( ( pim_include(*,G) (-) pim_exclude(S,G))
       (-) ( lost_assert(*,G) (+) lost_assert(S,G,rpt) ) )

Notes:

Left or right associativity is not established at the beginning of this document, so it is necessary to clarify which operations happens first.
