The exact controllability of a semilinear wave equation in a bounded open domain of R n , with controls on a part of the boundary and in the interior, is shown.. Feedback laws

In this paper we give the Nim value analysis of this game and show its relationship with Beatty’s Theorem.. The game is a one-pile counter pickup game for which the maximum number

We classify groups generated by powers of two Dehn twists which are free, or have no “unexpectedly reducible” elements.. In the end we pose similar problems for groups generated

Conley index, elliptic equation, critical point theory, fixed point index, superlinear problem.. Both authors are partially supportedby the Australian

Theorem 4.8 shows that the addition of the nonlocal term to local diffusion pro- duces similar early pattern results when compared to the pure local case considered in [33].. Lemma

The importance of our present work is, in order to construct many new traveling wave solutions including solitons, periodic, and rational solutions, a 2 1-dimensional Modi-

[18] , On nontrivial solutions of some homogeneous boundary value problems for the multidi- mensional hyperbolic Euler-Poisson-Darboux equation in an unbounded domain,

Using this characterization, we prove that two covering blocks (which in the distributive case are maximal Boolean intervals) of a free bounded distributive lattice intersect in
