theorem Th14: :: KURATO_2:14

for n being Nat
for S being SetSequence of the carrier of (TOP-REAL n)
for p being Point of (TOP-REAL n)
for p9 being Point of (Euclid n) st p = p9 holds
( p in Lim_inf S iff for r being Real st r > 0 holds
ex k being Nat st
for m being Nat st m > k holds
S . m meets Ball (p9,r) )
