Zeta functions and modularity of Calabi-Yau manifolds
Published 2018“…</p> <p>This expansion provides an efficient means to compute a quartic factor R(T) of the local zeta function, not just for the quintic but for a large number of one parameter families of Calabi-Yau manifolds. We exploit the miraculous fact that U(λ) becomes a rational function mod p<sup>4</sup> to avoid evaluating the series for U(λ) directly. …”

Generalized Lagrangian mean curvature flow in almost Calabi-Yau manifolds
Published 2011“…</p><p>The second problem we study is the short time existence problem for the generalized Lagrangian mean curvature flow in almost Calabi-Yau manifolds, when the initial Lagrangian submanifold has isolated conical singularities that are modelled on stable special Lagrangian cones. …”

Holomorphic Yukawa couplings in heterotic string theory
Published 2021“…We then specialise to a class of heterotic string models for which the vector bundle is split into a sum of line bundles and the Calabi-Yau manifold is defined as a complete intersection in projective ambient spaces.…”

Superstrings
Published 1986“…Further reduction of the gauge group and emergence of naturally light weak Higgs doublets may also occur by flux breaking if the Calabi Yau manifold is multiply connected. We analyse the feasibility of such scenarios for Calabi Yau manifolds with any possible fundamental group. …”

Calabi-Yau threefolds and heterotic string compactification
Published 2010“…We construct a large number of new examples via free group actions on complete intersection Calabi-Yau manifolds (CICY's). For special values of the parameters, these group actions develop fixed points, and we show that, on the quotient spaces, this leads to a particular class of singularities, which are quotients of the conifold. …”

Heterotic string compactification and quiver gauge theory on toric geometry

Aspects of string model building and heterotic/F-theory duality
Published 2019“…We focus on the simpler case of complex surfaces as a step towards understanding the case of Calabi-Yau manifolds. These surfaces can also be used as bases for elliptic three- folds, and their cohomology lifted via the Leray spectral sequence. …”

Calabi-Yau categories and quivers with superpotential
Published 2014“…Hence quivers with superpotential can be viewed as noncommutative Calabi- Yau manifolds.</p> <p>One might then ask if there are derived equivalences between Calabi-Yau manifolds and quivers with superpotential. …”
