The one-one equivalence of some general combinatorial decision problems
1. Introduction. A decision problem for a combinatorial system shall denote a pair ($, S) where is a specified kind of decision problem (e.g. derivability problem, halting problem, etc.) and 5 is a combina-torial system. Two decision problems (<£i, Si), ($ 2 , £2) are sa ^d t0 be of the same many-one degree (of unsolvability) if there exist effective many-one mappings ƒ and g such that each...
متن کاملSignature submanifolds for some equivalence problems
This article concerned on the study of signature submanifolds for curves under Lie group actions SE(2), SA(2) and for surfaces under SE(3). Signature submanifold is a regular submanifold which its coordinate components are differential invariants of an associated manifold under Lie group action, and therefore signature submanifold is a key for solving equivalence problems.
متن کاملSome combinatorial problems of importance
We discuss two combinatorial problems for which we have only sub-optimal solutions. We describe known solutions and we explain why better solutions would be of importance to Cryptography. The areas of application are in improving the ef-ciency of Zero-Knowledge proofs, in relating the quadratic residuosity problem to the problem of integer factorization, and in analyzing some cryptographic sche...

متن کاملSome Combinatorial Problems in the Plane
1 Let there be given n points in the plane. Denote by t i the number of lines which contain exactly i of the points (2 < i < n). The properties of the set {ti } have been studied a great deal. For example, there is the classical result of Gallai and Sylvester : Assume to = 0 (i .e ., the points are not all on one line) ; then t2 > 0. For the history of this problem see, e.g ., Motzkin [6] and E...
