Abstract: Let B(n)={(x_1,...,x_n) \in {1,2,3,...}^n: for each positive integers y_1,...,y_n the conjunction (\forall i,j,k \in {1,...,n} (x_i+x_j=x_k ==> y_i+y_j=y_k)) AND \forall i,j,k \in {1,......
Some man-made landscapes, such as plots of land may be viewed as Ttessellations,that is a tessellations of a subset of the plane, where all vertices are degree three and with one flat angle. Adamczyk ...
Using generalised dyadic cubes and the mass distribution principle, we give a straightforward new proof for the existence of doubling measures in complete doubling metric spaces.
We prove existence of regions minimizing perimeter under a volume constraint in contact sub-Riemannian manifolds such that their quotient by the group of contact transformations preserving the sub-Rie...
In a recent paper, Kiessling and Tahvildar-Zadeh proved that any spherically symmetric classical solution of the attractive relativistic Vlasov-Poisson equation launched by sufficiently regular initi...
Let $X,Y$ be two finite-dimensional topological vector spaces, $Z$ a Hausdorff topological vector space, $K\subset X$ and $D\subset Z$ be two nonempty sets, $C$ be a pointed, closed, and convex cone i...
