Theorem lshpset 29473
Description: The set of all hyperplanes of a left module or left vector space. The vector  v is called a generating vector for the hyperplane. (Contributed by NM, 29-Jun-2014.)
Hypotheses

lshpset.v  |-  V  =  ( Base `  W
)
lshpset.n  |-  N  =  ( LSpan `  W )
lshpset.s  |-  S  =  ( LSubSp `  W )
lshpset.h  |-  H  =  (LSHyp `  W )
Assertion
Ref Expression
lshpset  |-  ( W  e.  X  ->  H  =  { s  e.  S  |  ( s  =/= 
V  /\  E. v  e.  V  ( N `  ( s  u.  {
v } ) )  =  V ) } )
Distinct variable groups:    S, s    v, V    v, s, W
Allowed substitution hints:    S( v)    H( v, s)    N( v, s)    V( s)    X( v, s)

Proof of Theorem lshpset
Dummy variable  w is distinct from all other variables.
