Holomorphic anomaly of 2d Yang-Mills theory on a torus revisited

open access: yesJournal of High Energy Physics, 2019
We study the large N ’t Hooft expansion of the chiral partition function of 2d U(N) Yang-Mills theory on a torus. There is a long-standing puzzle that no explicit holomorphic anomaly equation is known for the partition function, although it admits a ...

A Goursat decomposition for polyharmonic functions in Euclidean space [PDF]

open access: yes, 2012
The Goursat representation formula in the complex plane, expressing a real–valued biharmonic function in terms of two holomorphic functions and their anti–holomorphic complex conjugates, is generalized to Euclidean space, expressing a real–valued ...

Analytic inversion of adjunction: L^2 extension theorems with gain [PDF]

open access: yes, 2005
We establish new results on weighted $L^2$ extension of holomorphic top forms with values in a holomorphic line bundle, from a smooth hypersurface cut out by a holomorphic function.

The General Warped Solution with Conical Branes in Six-dimensional Supergravity [PDF]

open access: yes, 2005
We present the general regular warped solution with 4D Minkowski spacetime in six-dimensional gauged supergravity. In this framework, we can easily embed multiple conical branes into the warped geometry by choosing an undetermined holomorphic function ...

On an Integral-Type Operator Acting between Bloch-Type Spaces on the Unit Ball

open access: yesAbstract and Applied Analysis, 2010
Let 𝔹 denote the open unit ball of ℂn. For a holomorphic self-map φ of 𝔹 and a holomorphic function g in 𝔹 with g(0)=0, we define the following integral-type operator: Iφgf(z)=∫01ℜf(φ(tz))g(tz)(dt/t), z∈𝔹.

Aspects of non-commutative function theory

open access: yesConcrete Operators, 2016
We discuss non commutative functions, which naturally arise when dealing with functions of more than one matrix variable.

Explicit black hole thermodynamics in natural variables

open access: yesJournal of High Energy Physics, 2023
We consider the general thermal asymptotically flat Kerr-Newman black holes in 4d Einstein-Maxwell theory. Even though their thermodynamics has been understood for decades, the Gibbs free energy and on-shell action are only known implicitly as functions ...

Upper and Lower Bounds for Essential Norm of Weighted Composition Operators from Bergman Spaces with Békollé Weights

open access: yesJournal of Function Spaces, 2020
Let σ be a weight function such that σ/1−z2α is in the class Bp0α of Békollé weights, μ a normal weight function, ψ a holomorphic map on D, and φ a holomorphic self-map on D.

Domain Identification for Inverse Problem via Conformal Mapping and Fixed Point Methods in Two Dimensions

open access: yesAbstract and Applied Analysis, 2020
In this paper, we present a survey of the inverse eigenvalue problem for a Laplacian equation based on available Cauchy data on a known part Γ0 and a homogeneous Dirichlet condition on an unknown part Γ0 of the boundary of a bounded domain, Ω⊂ℝN.

Note on boundedness of the $L$-index in the direction of the composition of slice entire functions

open access: yesМатематичні Студії, 2022
We study a composition of two functions belonging to a class of slice holomorphic functions in the whole $n$-dimensional complex space. The slice holomorphy in the space means that for some fixed direction $\mathbf{b}\in\mathbb{C}^n\setminus\{\mathbf{0}\
