Algorithms to test open set condition for self-similar set related to P.V. numbers
Fix a P.V. number Given
,
\mathbf{b}=(b_{1},\cdots,b_{m})\in \mathbb{Q^{m}, for the self-similar set
we find an efficient algorithm to
test whether satisfies the open set condition
(strong separation condition) or not
Order continuous extensions of positive compact operators on Banach lattices
Let and be Banach lattices. Let be a vector sublattice of and
be an order continuous positive compact (resp. weakly
compact) operators. We show that if is an ideal or an order dense
sublattice of , then has a norm preserving compact (resp. weakly
compact) positive extension to which is likewise order continuous on .
In particular, we prove that every compact positive orthomorphism on an order
dense sublattice of extends uniquely to a compact positive orthomorphism on
