## Abstract A (plane) 4βregular map __G__ is called __C__βsimple if it arises as a superposition of simple closed curves (tangencies are not allowed); in this case Ο (__G__) is the smallest integer __k__ such that the curves of __G__ can be colored with __k__ colors in such a way that no two curves
We construct a class of weak solutions to the NavierαStokes equations, which have second order spatial derivatives and one order time derivatives, of p power s Ε½ 2, r Ε½ .. summability for 1p F 5r4. Meanwhile, we show that u g L 0, T ; W β with 1rs q 3r2 r s 2 for 1r F 5r4. r can be relaxed not to ex
On p. 272 of the above article, paragraph # 3 is incomplete. It should read as the following: Hence to prove Proposition 4 it is enough to show that the edges of Q 4 can be colored with 4 colors in such a way that each square has one edge of each color. Such a coloring is displayed on the following
## Dedicated to the memory of Leonid R. Volevich Let X = (X1, . . . , Xm) be an infinitely degenerate system of vector fields. We study the existence and regularity of multiple solutions of the Dirichlet problem for a class of semi-linear infinitely degenerate elliptic operators associated with th
The existence and multiplicity of weak solutions is established for a class of concave-convex elliptic systems of the form: R 2 \ {(0, 0)}, the weight m(x) is a positive bounded function and a(x), b(x) β C (β¦) are functions which change sign in β¦. Our technical approach is based on the Nehari manifo
