definition
let a1 be non empty doubleLoopStr;
let a2 be non empty VectSpStr over a1;
let a3 be Element of bool the carrier of a2;
attr a3 is linearly-independent means

definiens
let a1 be non empty doubleLoopStr;
let a2 be non empty VectSpStr over a1;
let a3 be Element of bool the carrier of a2;
To prove
a3 is linearly-independent
it is sufficient to prove
thus for b1 being Linear_Combination of a3
st Sum b1 = 0. a2
holds Carrier b1 = {};

theorem
for b1 being non empty doubleLoopStr
for b2 being non empty VectSpStr over b1
for b3 being Element of bool the carrier of b2 holds
b3 is linearly-independent(b1, b2)
iff
for b4 being Linear_Combination of b3
st Sum b4 = 0. b2
holds Carrier b4 = {};
