The Kodaira dimension of some moduli spaces of elliptic K3 surfaces
Journal of the London Mathematical Society, Volume 104, Issue 1, Page 269-294, July 2021., 2021 Abstract We study the moduli spaces of elliptic K3 surfaces of Picard number at least 3, that is, U⊕⟨−2k⟩‐polarized K3 surfaces. Such moduli spaces are proved to be of general type for k⩾220. The proof relies on the low‐weight cusp form trick developed by Gritsenko, Hulek and Sankaran.

A general approach to infinite-dimensional holomorphy
Monatshefte f�r Mathematik, 1986 The purpose of the paper is to present a frame for a theory of holomorphic functions between locally convex spaces and bornological vector spaces respectively. Using continuous convergence [see \textit{E. Binz}, Lect. Notes Math. 469 (1975; Zbl 0306.54003)] instead of topologies on spaces of holomorphic functions a very general theory, which is ...

Extending polynomials in maximal and minimal ideals [PDF]
, 2010 Given an homogeneous polynomial on a Banach space $E$ belonging to some maximal or minimal polynomial ideal, we consider its iterated extension to an ultrapower of $E$ and prove that this extension remains in the ideal and has the same ideal norm.

Perturbation Theory of Schr\"odinger Operators in Infinitely Many Coupling Parameters
, 1999 In this paper we study the behavior of Hamilton operators and their spectra which depend on infinitely many coupling parameters or, more generally, parameters taking values in some Banach space. One of the physical models which motivate this framework is

Approximation of high-dimensional parametric PDEs [PDF]
, 2015 Parametrized families of PDEs arise in various contexts such as inverse problems, control and optimization, risk assessment, and uncertainty quantification. In most of these applications, the number of parameters is large or perhaps even infinite.

Stability of Sasaki-extremal metrics under complex deformations [PDF]
, 2012 We consider the stability of Sasaki-extremal metrics under deformations of the complex structure on the Reeb foliation. Given such a deformation preserving the action of a compact subgroup of the automorphism group of a Sasaki-extremal structure, a ...

Journal of the London Mathematical Society, Volume 111, Issue 5, May 2025.Abstract Using iterated uniform local completion, we introduce a notion of continuous CR$CR$ functions on locally closed subsets of reduced complex spaces, generalising both holomorphic functions and CR$CR$ functions on CR$CR$ submanifolds. Under additional assumptions of set‐theoretical weak pseudo‐concavity, we prove optimal maximum modulus ...

Linear structure of the weighted holomorphic non-extendibility [PDF]
, 2006 In this paper, it is proved that, for any domain G of the complex plane, there exist an infinite-dimensional closed linear submanifold M1 and a dense linear submanifold M2 with maximal algebraic dimension in the space H(G) of holomorphic functions on G ...
