We show that there exists a bounded subset of R such that no system of exponentials can be a Riesz basis for the corresponding Hilbert space. An additional result gives a lower bound for the Riesz constant of any putative Riesz basis of the two dimensional disk. 
A note on exponential Riesz bases
We prove that if Il = [al, bl), l = 1, . . . , L, are disjoint intervals in [0, 1) with the property that the numbers 1, a1, . . . , aL, b1, . . . , bL are linearly independent over Q, then there
Exponential bases with hierarchical structure
We prove that if Il, l = 1, . . . , L, are disjoint separated intervals in [0, 1), then there exist pairwise disjoint sets Λl ⊂ Z, l = 1, . . . , L, such that for every J ⊂ {1, . . . , L}, the system
A characterization of Gabor Riesz bases with separable time-frequency shifts
A Gabor system generated by a window function g ∈ L(R) and a separable set Λ×Γ ⊂ R is the collection of time-frequency shifts of g given by G(g,Λ×Γ) = { e2πiξ·tg(t− x) } (x,ξ)∈Λ×Γ. One of the

On construction of bounded sets not admitting a general type of Riesz spectrum
Despite the recent advances in the theory of exponential Riesz bases, it is yet unknown whether there exists a set S ⊂ R which does not admit a Riesz spectrum, meaning that for every Λ ⊂ R the set of
Riesz bases of exponentials and multi-tiling in finite abelian groups
Motivated by the open problem of exhibiting a subset of Euclidean space which has no exponential Riesz basis, we focus on exponential Riesz bases in finite abelian groups. We point out that that
Combining Riesz bases
We show that any finite union of intervals supports a Riesz basis of exponentials.
A simple construction of exponential bases in L2 of the union of several intervals
Riesz bases of complex exponentials in the space L(I), where / is a finite interval of R, have been thoroughly explored since the possibility of nonharmonic Fourier expansions was discovered by Paley
Fuglede’s conjecture for a union of two intervals
We prove that a union of two intervals in R is a spectral set if and only if it tiles R by translations.
