Weak Linking Theorems and Schrödinger Equations with Critical Sobolev Exponent

Martin Schechter, Wenming Zou (2010)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

In this paper we establish a variant and generalized weak linking theorem, which contains more delicate result and insures the existence of bounded Palais–Smale sequences of a strongly indefinite functional. The abstract result will be used to study the semilinear Schrödinger equation - Δ u + V ( x ) u = K ( x ) | u | 2 * - 2 u + g ( x , u ) , u W 1 , 2 ( 𝐑 N ) , where ≥ 4; are periodic in x for 1 ≤ ≤ and 0 is in a gap of the spectrum of -Δ + ; . If 0 < g ( x , u ) u c | u | 2 * for an appropriate constant , we show that this equation has a nontrivial solution.

Minimax nonparametric hypothesis testing for ellipsoids and Besov bodies

Yuri I. Ingster, Irina A. Suslina (2010)

ESAIM: Probability and Statistics

Similarity:

We observe an infinitely dimensional Gaussian random vector where is a sequence of standard Gaussian variables and is an unknown mean. We consider the hypothesis testing problem alternatives H ε , τ : v V ε for the sets V ε = V ε ( τ , ρ ε ) l 2 . The sets are -ellipsoids of semi-axes with -ellipsoid of semi-axes removed or similar Besov bodies with Besov bodies removed. Here τ = ( κ , R ) or τ = ( κ , h , t , R ) ; κ = ( p , q , r , s ) are the parameters which define the sets for given radii , 0 < ; is the asymptotical...

About the decision of reachability for register machines

RAIRO - Theoretical Informatics and Applications

Similarity:

We study the decidability of the following problem: given  affine functions ƒ,...,ƒ over k and two vectors v 1 , v 2 k , is reachable from by successive iterations of ƒ,...,ƒ (in this given order)? We show that this question is decidable for and undecidable for some fixed .

RAIRO - Theoretical Informatics and Applications

Similarity:

A vertex of a graph = () is said to be by M V if the majority of the elements of the neighborhood of  (including itself) belong to . The set is a in if every vertex i V is controlled by . Given a set M V and two graphs = ( V , E 1 ) and = ( V , E 2 ) where E 1 E 2 , the consists of deciding whether there exists a sandwich graph = () (, a graph where E 1 E E 2 ) such that is a monopoly in = (). If the answer to the is No, we then consider the , whose objective is to find a sandwich...
