On Interpolation by Functions in
Raymond Cheng, Christopher Felder
This work explores several aspects of interpolating sequences for , the space of analytic functions on the unit disk with -summable Maclaurin coefficients. Much of thi…
Geometry of -bic Hypersurfaces
Raymond Cheng
Traditional algebraic geometric invariants lose some of their potency in positive characteristic. For instance, smooth projective hypersurfaces may be covered by lines despite bein…
Zeros of optimal polynomial approximants in
Raymond Cheng, William T. Ross, Daniel Seco
The study of inner and cyclic functions in spaces requires a better understanding of the zeros of the so-called optimal polynomial approximants. We determine that a poin…
Unbounded negativity on rational surfaces in positive characteristic
Raymond Cheng, Remy van Dobben de Bruyn
We give explicit blowups of the projective plane in positive characteristic that contain smooth rational curves of arbitrarily negative self-intersection, showing that the Bounded…
Inner vectors for Toeplitz operators
Raymond Cheng, Javad Mashreghi, William T. Ross
In this paper we survey and bring together several approaches to obtaining inner functions for Toeplitz operators. These approaches include the classical definition, the Wold decom…
Inner functions in reproducing kernel spaces
Raymond Cheng, Javad Mashreghi, William T. Ross
In this paper we explore the notion of inner function in a broader context of operator theory.
