Abstract:For Newtonian N+k–body problems in R^2, we prove the existence of new noncollision periodic solutions such that N + k bodies move on two different closed curves and have some given winding numbers. | |||

Abstract:The well-known invariant subspace problem is A long-standing problem in operator theory,which has been to determine whether every (bounded linear) operator $T$ on a Banach space $X$ must have a nontrivial invariant subspace. every reducible subspace of $T$ is invariant subspace of $T$ too. We show that, for some Banach space operators $T$,( {\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\it bi-crystal} operator) the following statements are equivalent. (1) There exists a nontrivial invariant subspace of $T$. (2) $T$ is Banach reducible. (3) $T$ is reflexive. And we show that if $A\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\sim A \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\bigoplus A$, then $A$ is reflexive. | |||

Abstract:This paper is concerned with the existence and multiplicity solutions to a class of p(x)- Kirchhoff-type problem with Dirichlet boundary data. By means of a direct variational approach and the theory of the variable exponent Sobolev spaces, we establish conditions ensuring the existence and multiplicity of solutions for the problem. | |||

Abstract:We prove that given an affine IFS on the real line and a probability vector then there exists a corresponding combinatorial identity associated with binomial coefficients and moment sequence with respect to the invariant measure $mu$ of the IFS. In particular, when $mu$ is the restriction of Lebesgue measure to a close interval, we obtain some well-known or unknown combinatorial identities. | |||

Abstract:We introduce a new Hausdorff type measure on plane and define a new dimension print associated with this measure. Our main theorems show that this measure is just the generalization of Lebesgue measure and the new dimension print contains more information than the usual one. | |||
