Summing up Open String Instantons and N=1 String Amplitudes [PDF]

open access: yes, 2002
We compute the instanton expansions of the holomorphic couplings in the effective action of certain $\cx N=1$ supersymmetric four-dimensional open string vacua. These include the superpotential $W(\phi)$, the gauge kinetic function $f(\phi)$ and a series

On the Implications of Discrete Symmetries for the Beta Function of Quantum Hall Systems

open access: yes, 1998
We argue that the large discrete symmetry group of quantum Hall systems is insufficient in itself to determine the complete beta function for the scaling of the conductivities, $\sigma_{xx}$ and $\sigma_{xy}$.

M-theory on pp-waves with a holomorphic superpotential and its membrane and matrix descriptions [PDF]

open access: yes, 2008
We study a new class of inhomogeneous pp-wave solutions with 8 unbroken supersymmetries in D=11 supergravity. The 9 dimensional transverse space is Euclidean and split into 3 and 6 dimensional subspaces.

Nontautological cycles on moduli spaces of smooth pointed curves

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract In recent work by Arena, Canning, Clader, Haburcak, Li, Mok, and Tamborini, it was proven that for infinitely many values of g$g$ and n$n$, there exist nontautological algebraic cohomology classes on the moduli space Mg,n$\mathcal {M}_{g,n}$ of smooth genus g$g$, n$n$‐pointed curves.

Volterra composition operators from generalized weighted weighted Bergman spaces to µ-Bloch spaces

open access: yesJournal of Function Spaces and Applications, 2009
Let φ be a holomorphic self-map and g be a fixed holomorphic function on the unit ball B. The boundedness and compactness of the operator Tg,φf(z)=∫01f(φ(tz))ℜg(tz)dtt from the generalized weighted Bergman space into the µ-Bloch space are studied in this

’t Hooft anomalies and the holomorphy of supersymmetric partition functions

open access: yesJournal of High Energy Physics, 2019
We study the dependence of supersymmetric partition functions on continuous parameters for the flavor symmetry group, G F , for 2d N $$ \mathcal{N} $$ = (0, 2) and 4d N $$ \mathcal{N} $$ = 1 supersymmetric quantum field theories.

A heterotic Kodaira-Spencer theory at one-loop

open access: yesJournal of High Energy Physics, 2023
We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be expressed as a product of holomorphic Ray-Singer torsions.

Analytic cliffordian functions [PDF]

open access: yes, 2004
In classical function theory, a function is holomorphic if and only if it is complex analytic. For higher dimensional spaces it is natural to work in the context of Clifford algebras. The structures of these algebras depend on the parity of the dimension

Kaehler Manifolds of Quasi-Constant Holomorphic Sectional Curvatures

open access: yes, 2005
The Kaehler manifolds of quasi-constant holomorphic sectional curvatures are introduced as Kaehler manifolds with complex distribution of codimension two, whose holomorphic sectional curvature only depends on the corresponding point and the geometric ...

Faber's socle intersection numbers via Gromov–Witten theory of elliptic curve

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract The goal of this very short note is to give a new proof of Faber's formula for the socle intersection numbers in the tautological ring of Mg$\mathcal {M}_g$. This new proof exhibits a new beautiful tautological relation that stems from the recent work of Oberdieck–Pixton on the Gromov–Witten theory of the elliptic curve via a refinement of ...
