متن کاملThe Vámos Network
The well-studied Vámos matroid has provided a wealth of interesting theoretical results in matroid theory. We use the Vámos matroid to construct a new network, which we call the Vámos network. We then exploit the Vámos network to answer in the negative the open question as to whether Shannon-type information inequalities are in general sufficient for computing network coding capacities. To acco...
متن کاملImproved upper bounds for the information rates of the secret sharing schemes induced by the Vámos matroid
An access structure specifying the qualified sets of a secret sharing scheme must have information rate less than or equal to one. The Vamos matroid induces two non-isomorphic access structures V1 and V6, which were shown by Mart́ı-Farré and Padró to have information rates of at least 3/4. Beimel, Livne, and Padró showed that the information rates of V1 and V6 are bounded above by 10/11 and 9/10...
متن کاملPolynomial Iungs over Jacobsoñ-hilbert Rings
CARL FAITH All rings considered are commutative with unit. A ring R is SISI (in Vámos' terminology) if every subdirectly irreducible factor ring R/I is self-injective . SISI rings include Noetherian rings, Morita rings, and almost maximal valuation rings ([Vil) . In [F3] we raised the question of whether a polynomial ring R[-1 over a SISI ring R is again SISI . In this paper we show this is not...
