Theorem gsumfzsnfd 13903

Description: Group sum of a singleton, deduction form, using bound-variable hypotheses instead of distinct variable conditions. (Contributed by Mario Carneiro, 19-Dec-2014.) (Revised by Thierry Arnoux, 28-Mar-2018.) (Revised by AV, 11-Dec-2019.)

Hypotheses

Ref	Expression
gsumsnd.b	|- B = ( Base ` G )
gsumsnd.g	|- ( ph -> G e. Mnd )
gsumfzsnd.m	|- ( ph -> M e. ZZ )
gsumsnd.c	|- ( ph -> C e. B )
gsumsnd.s	|- ( ( ph /\ k = M ) -> A = C )
gsumsnfd.p	|- F/ k ph
gsumsnfd.c	|- F/_ k C

Assertion

Ref	Expression
gsumfzsnfd	|- ( ph -> ( G gsumg ( k e. { M } |-> A ) ) = C )

Distinct variable group:   k, M

Allowed substitution hints:   ph( k)   A( k)   B( k)   C( k)   G( k)
