Probabilistic Existence Results for Separable Codes [PDF]
IEEE Transactions on Information Theory, 2015 Separable codes were defined by Cheng and Miao in 2011, motivated by applications to the identification of pirates in a multimedia setting. Combinatorially, $\overline{t}$-separable codes lie somewhere between $t$-frameproof and $(t-1)$-frameproof codes: all $t$-frameproof codes are $\overline{t}$-separable, and all $\overline{t}$-separable codes are $(

On relaxation of state-constrained optimal control problem in coefficients for biharmonic equation
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2015 We study a Dirichlet optimal control problem for biharmonic equation withcontrol and state constraints. The coecient of the biharmonic operator, the weightu, we take as a control in L1(Ω).

Existence results for an elliptic DirichletI problem
Le Matematiche, 2011 The main purpose of this paper is to present recent existence results for an elliptic eigenvalue Dirichlet problem. Precisely, our method ensures the existence of an exactly determined open interval (possibly unbounded) of positive parameters for which the problem admits infinitely many weak solutions.

EXISTENCE AND NON-EXISTENCE RESULTS FOR WAVE OPERATORS FOR PERTURBATIONS OF THE LAPLACIAN [PDF]
Reviews in Mathematical Physics, 1993 Schrödinger operators with time-dependent potentials are studied. Necessary and sufficient conditions for existence of ordinary and Dollard-type modified wave operators are obtained. Sharp results for potentials with a specified leading term are obtained. Applications are given to the surfboard Schrödinger equation and to Stark Hamiltonians.

Existence and non-existence results for strong external difference families [PDF]
Discrete Mathematics, 2018 We consider strong external difference families (SEDFs); these are external difference families satisfying additional conditions on the patterns of external diferences that occur, and were first defined in the context of classifying optimal strong algebraic manipulation detection codes.

Existence Result and Uniqueness for Some Fractional Problem
Mathematics, 2019 In this article, by the use of the lower and upper solutions method, we prove the existence of a positive solution for a Riemann−Liouville fractional boundary value problem. Furthermore, the uniqueness of the positive solution is given.

AN EXISTENCE RESULT FOR ANISOTROPIC QUASILINEAR PROBLEMS
, 2022 We study existence of solutions for a boundary degenerate (or singular) quasilinear equation in a smooth bounded domain under Dirichlet boundary conditions. We consider a weighted p−Laplacian operator with a coefficient that is locally bounded inside the

Generalized Active Contour Model in an Anisotropic Variable Exponent Sobolev Space
Journal of Optimization, Differential Equations and Their ApplicationsMostly motivated by the practical applications especially in the field of satellite remote sensing of agricultural territories, we develop a novel approach to the domain decomposition basing on the anisotropic version of the Chan-Vese active contour ...

Journal of Inequalities and Applications, 2023 The logical progression from the constant order differential equations is the field of variable-order differential equations. Such equations can frequently give a more succinct description of problems in the real world.
