Probabilistic Existence Results for Separable Codes [PDF]

open access: yesIEEE 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 $(

A general existence result for the Toda system on compact surfaces [PDF]

open access: yes, 2013
In this paper we consider the following Toda system of equations on a compact surface: {−Δu1=2ρ1(h1eu1∫Σh1eu1dVg−1)−ρ2(h2eu2∫Σh2eu2dVg−1)−Δu1=−4π∑j=1mα1,j(δpj−1),−Δu2=2ρ2(h2eu2∫Σh2eu2dVg−1)−ρ1(h1eu1∫Σh1eu1dVg−1)−Δu2=−4π∑j=1mα2,j(δpj−1), which is ...

On relaxation of state-constrained optimal control problem in coefficients for biharmonic equation

open access: yesVìsnik 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 result for a class of coupled fractional differential systems with integral boundary value conditions

open access: yes, 2017
Applying coincidence degree theory of Mawhin, this paper is concerned with existence result for a coupled fractional differential systems with Riemann-Stieltjes integral boundary value conditions. An example is also given to illustrate the main result. c

On existence of optimal controls in coecients for ill-posed nonlinear elliptic Dirichlet boundary value problems with anisotropic p-Laplacian

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2016
We study a Dirichlet optimal control problem for a nonlinear elliptic anisotropic p-Laplace equation with control and state constraints. The matrix-valued coecients we take as controls and in the linear part of dierential operator we consider coecients ...

Uniqueness and Existence Results

open access: yes, 2022
AbstractIn this chapter, we establish Theorems 10.1007/978-3-030-95088-0_1#FPar4 and 10.1007/978-3-030-95088-0_1#FPar5 and show that, under the assumptions of these theorems, the sequence $$n\mapsto f^p_n[g]$$ n ↦ f

An existence result for the mean-field equation on compact surfaces in a doubly supercritical regime [PDF]

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2012
We consider a class of variational equations with exponential nonlinearities on a compact Riemannian surface, describing the mean-field equation of the equilibrium turbulence with arbitrarily signed vortices.

Existence results for an elliptic DirichletI problem

open access: yesLe 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 strong external difference families [PDF]

open access: yesDiscrete 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.
