✦ Synopsis
We prove in this paper that, given ␣ g 0, 1r2 , there exists a linear manifold M of entire functions satisfying that M is dense in the space of all entire functions Ž< < ␣ . Ž j. Ž . and, in addition, lim exp z f z s0 on any plane strip for every f g M z ª ϱ and for every derivation index j. Moreover, it is shown the existence of an entire function with infinite growth index satisfying the latter property.

In this note we construct an odd weight function w on (-1,l) with w ( x ) > 0 for x > 0 such that the eigenfunctions of the indefinite Sturm-Liouville problem -f" = Xwf with boundary conditions f(-1) = f(1) = 0 do not form a FLiesz basis of L f w , ( -l , 1).
## Abstract We shall explicitly evaluate important constants in embedding theorems and Hölder‐regularity theorems for an elliptic equation of the type magnified image.
The kernel of a certain triangular derivation of the polynomial ring k x 1 x 2 x 3 x 4 x 5 is shown to be non-finitely generated over k (a field of characteristic zero), thus giving a new counterexample to Hilbert's Fourteenth Problem, in the lowest dimension to date.
