Compact isospectral sets of plane domains.

Any isospectral family of two-dimensional Euclidean domains is shown to be compact in the C(infinity) topology. Previously Melrose, using heat invariants, was able to establish the C(infinity) compactness of the curvature of the boundary curves. The additional ingredient used in this paper to obtain the compactness of the domains is the behavior of the determinant of the Laplacian near the boun...

Isospectral Sets of Drumheads Are Compact in C ∞

0 κ0κ1 1 · · ·κ αk−1 k−1 ds , k ≥ 3 . Here ck 6= 0 and the sum, which is finite, consists of lower order terms in the sense that αk−1 ≤ 2. The bk+1 therefore bound the corresponding Sobolev norms on κ and the compactness, in the C∞ topology on κ, of the set of domains with a fixed spectrum follows. The coefficients a0, a1, a2, a3, b0, b1, b2 have already been computed, see L. Smith [5] and the ...

A convex combinatorial property of compact sets in the plane and its roots in lattice theory

K. Adaricheva and M. Bolat have recently proved that if $,mathcal U_0$ and $,mathcal U_1$ are circles in a triangle with vertices $A_0,A_1,A_2$, then there exist $jin {0,1,2}$ and $kin{0,1}$ such that $,mathcal U_{1-k}$ is included in the convex hull of $,mathcal U_kcup({A_0,A_1, A_2}setminus{A_j})$. One could say disks instead of circles.Here we prove the existence of such a $j$ and $k$ ...

Normed Algebras of Differentiable Functions on Compact Plane Sets

We investigate the completeness and completions of the normed algebras (D(1)(X), ‖ · ‖) for perfect, compact plane sets X. In particular, we construct a radially self-absorbing, compact plane set X such that the normed algebra (D(1)(X), ‖ · ‖) is not complete. This solves a question of Bland and Feinstein. We also prove that there are several classes of connected, compact plane sets X for which...
