Duality under dependency inversion and noether theory for second-order lagrangians

open access: yesInternational Journal of Solids and Structures, 1986
Par dualité on comprend la correspondance entre deux processus de la mécanique continue où les variables dépendantes sont échangées par les variables indépendantes, c'est une généralisation de la théorie du champ classique [\textit{R. T. Shield}, Z. Angew. Math. Phys. 18, 490-500 (1967; Zbl 0146.461)]. Le travail considère la dualité dans un lagrangien

Unfolding the high orders of asymptotic expansions with coalescing saddles: singularity theory, crossover and duality

Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1993
Abstract We study the leading behaviour of the late coefficients (high orders r) of asymptotic expansions in a large parameter k, for contour integrals involving a cluster of coalescing saddles, and thereby establish the form of the divergence of the expansions.

Applications of Duality in the Theory of Finitely Generated Lattice-Ordered Abelian Groups

Canadian Journal of Mathematics, 1977
In a previous paper by the author [3], duality theorems for finitely generated vector lattices and lattice-ordered Abelian groups are described. In particular, the category of finitely generated semi-simple vector lattices is shown to be equivalent to a geometrical category V whose objects are topologically closed cones in Euclidean space, and whose ...

Duality Theory and Transfers for Stochastic Order Relations

2013
In this paper it will be demonstrated how functional analytic tools from duality theory can be used to give interesting characterizations of stochastic order relations for discrete distributions in terms of mass transfer principles. A general result for a large class of integral stochastic orders will be derived, and it will be shown that this applies ...

Duality Theory fornth Order Differential Operators under Stieltjes Boundary Conditions

SIAM Journal on Mathematical Analysis, 1975
The adjoint of an nth order vector-valued linear differential system with boundary conditions represented by singular matrix-valued measures is constructed when the system is viewed as an operator with domain and range in a space of $L^p $ integrable functions. Both the operator and its adjoint are shown to be normally solvable.

Duality theory forN-th order differential operators under stieltjes boundary ponditions. II: Nonsmooth coefficients and nonsingular measures

Annali di Matematica Pura ed Applicata, 1975
Adjoint relations are characterized for an n-th order vector valued differential system with nonsmooth coefficients and with boundary conditions represented by Stieltjes measures of bounded variation when the system is viewed as an operator with domain and range in a space of Lp integrable functions.

Entropy and Order: A Duality in Topos Theory

In the last decades, the theory of Categories introduced deep changes in the way math and physics are conceived, introducing new objects, theorems and laws. This sort work introduces an innovative theorem, which investigates the duality between entropy and order within the framework of a topos, a fundamental concept in category theory.
