PlÃ¼cker coordinates of finite-dimensional subspaces of $ℓ^{p}$ and its direct sums: summability, reconstruction, stratification

David Victor Feldman

An $n$ -dimensional subspace of $ℓ^{p}$ has PlÃ¼cker coordinates indexed by the $n$ -element subsets of $N$ . We show these coordinates lie in $\ell^p\In{n}$ --- the exponent is pre…

Non-isomorphism of rings of integer-coefficient holomorphic functions on disks of varying radius

Jon Bannon, David Feldman

For $I ¨ \in (0, 1]$ , let $R (I ¨ ) = Z [[z]] \cap O (B (0, I ¨ ))$ denote the ring of power series with integer Taylor coefficients converging on the open disk $B (0, I ¨ )$ . We prove th…

Integer Coefficient Power Series with Prescribed Zero Sets

Jon Bannon, David Feldman

We prove that a discrete effective divisor on the open unit disk $D$ is the zero divisor of a holomorphic function on $D$ with integer Taylor coefficients if and…

Anomalous Partial Quotients in the Continued Fraction of $I^¶ (3) - S_{N}$

David Victor Feldman

Let $S_{N} = \sum_{j = 1}^{N} j^{- 3}$ and $R_{N} = I^¶ (3) - S_{N}$ . The simple continued fraction of $R_{N}$ has partial quotients of generic size $O (N)$ . We prove that at the sequence o…
