Abstract

In this paper, we study analytic multiplier ideal sheaves of toric plurisubharmonic functions on normal affine toric complex analytic spaces equipped with torus-invariant rational divisors, assuming that a positive integer multiple of the log canonical divisor is Cartier. We describe these sheaves in terms of Newton convex bodies and show that they are globally generated by finitely many meromorphic monomials. Our results generalize the description of An and the formulas of Howald and Blickle for monomial ideals, and recover the descriptions of Rashkovskii and Guenancia on affine space. We also extend this description to weights obtained by subtracting positive rational multiples of monomial ideal weights.

Some properties of extremal functions in the Krzyz problem

Krzyz's conjecture on estimating the moduli of Taylor coefficients in the class of holomorphic, bounded, nonvanishing functions is considered. This paper studies both global and locally extremal functions in the introduced topology, which is stronger than the topology of locally uniform convergence. The relation between the class under consideration and the Caratheodory class is established, and the general form of extremal functions in the Krzyz problem is described. It is shown that every extremal function corresponds to a polynomial $H$ generated by its coefficients and having positive real part in the unit disk. These polynomials are studied using a finite-dimensional analogue of the Caratheodory-Toeplitz criterion for polynomials, following from the Fejer-Riesz theorem. Necessary extremality conditions are obtained that substantially simplify the study of extremals for fixed $n$. Conditions for uniqueness of an extremal function are investigated. In particular, it is proved that uniqueness of a global extremal implies the Krzyz conjecture. The notion of functions of extremal type, satisfying all the necessary extremality conditions obtained, is introduced. Every locally extremal function is of extremal type, and the search for such functions at a fixed coefficient index reduces to solving a finite system of equations and inequalities. The sets of functions of extremal type are completely described for $n=1,2,3$. It is proved that the set of functions of extremal type consists of one function for $n=1$, five functions for $n=2$, and nineteen functions for $n=3$. Comparing the values of the functional under study on these sets proves the Krzyz conjecture for $n=1,2,3$.

New Taylor and Laurent series of axially harmonic, Fueter regular and polyanalytic functions

The Fueter-Sce mapping theorem stands as one of the most profound outcomes in complex and hypercomplex analysis, producing hypercomplex generalizations of holomorphic functions. In recent years, delving into the factorization of the second operator appearing in the Fueter-Sce mapping theorem has uncovered its potential to generate novel classes of functions and their respective functional calculi. The sets of functions obtained from this factorization and the associated functional calculi define the so-called {\em fine structures on the $S$-spectrum}. This paper aims to comprehensively investigate the function theories for the fine structures of Dirac type in the quaternionic framework, presenting new series expansions for axially harmonic, Fueter regular, and axially polyanalytic functions. These series expansions are highly nontrivial. In fact, when considering the hypercomplex realm, specifically the quaternionic or the Clifford setting, extending the concept of complex power series expansion is not immediate, and different Taylor and Laurent expansions appear with different sets of convergence. Additionally, our objectives include establishing the representation formulas for these function spaces; such formulas encode the fundamental properties of the functions and have numerous consequences. Finally, in the last section of this paper, we explain the applications of the fine structures in operator theory.
