An Alternative Proof for the MacWilliams Identity
, 2007
"... This paper provides an alternative proof to the MacWilliams identity for linear block codes over GF(qm). The intermediate results of our alternative proof offer some insights of the vectorspace structure. Our vectorspacebased methodology can be used to establish the relation between weight distri ..."

An Alternative Proof of the Greville Formula
 Journal of Optimization Theory and Applications
, 1997
"... Abstract. A simple proof of the Greville formula for the recursive computation of the MoorePenrose (MP) inverse of a matrix is presented. The proof utilizes no more than the elementary properties of the MP inverse. Key Words. MoorePenrose inverse, simple proof for recursive relation, Greville form ..."

Another alternative proof of Effros’ theorem
 Top. Proc
, 1987
"... After its discovery by Ungar [8] in 1975, the socalled Effros theorem has become a central tool in the study of homogenous continua. (See e.g. [2], [7].) This important result (actually a corollary to the original result in ..."

An alternative proof of SAT NPcompleteness
"... Nous donnons une preuve de la NPcomplétude de SAT en se basant sur une caractérisation logique de la classe NP donnée par Fagin en 1974. Ensuite, nous illustrons une partie de la preuve en montrant comment deux problèmes bien connus, le problème de MAX STABLE et de 3COLORATION peuvent s’exprimer s ..."

’exprimer sous forme conjonctive normale. Enfin, dans le même esprit, nous redémontrons la min NPOcomplétude du problème de MIN WSAT sous la stricteréduction. Motsclefs: logique du second ordre, NPcomplétude, réductions. We give a proof of SAT’s NPcompleteness based upon a syntaxic characterization of NP
Alternative proof for the localization of Sinai’s walk
, 2005
"... We give an alternative proof of the localization of Sinai’s random walk in random environment under weaker hypothesis than the ones used by Sinai. Moreover we give estimates that are stronger than the one of Sinai on the localization neighborhood and on the probability for the random walk to stay ..."

StrategyProofness and Arrow’s Conditions: Existence and Correspondence Theorems for Voting Procedures and Social Welfare Functions
 J. Econ. Theory
, 1975
"... Consider a committee which must select one alternative from a set of three or more alternatives. Committee members each cast a ballot which the voting procedure counts. The voting procedure is strategyproof if it always induces every committee member to cast a ballot revealing his preference. I pro ..."

An Alternative Proof of the WellFoundedness of the Nested Multiset Ordering
"... This research note outlines an alternative proof of the wellfoundedness of the nested multiset ordering. It is first shown that the set M∗(S) of nested multisets over a given base set S forms a cumulative type structure. Then, by exploiting the notion of sets bounded in rank, it is proved that (M∗ ..."
