Monopolist’s mark-up and the elasticity of substitution
Croatian Operational Research Review, 2017 This paper analyzes the mark-up of the price of a product over marginal costs for a monopolist using Appelbaum’s theoretical model. The profit maximization model of an industry that uses the monopolist’s product as its input is formulated. Our goal is to

Nongeometric heterotic strings and dual F-theory with enhanced gauge groups [PDF]
Journal of High Energy Physics, 2018 A bstractEight-dimensional nongeometric heterotic strings were constructed as duals of F-theory on Λ1,1 ⊕ E8 ⊕ E7 lattice polarized K3 surfaces by Malmendier and Morrison. We study the structure of the moduli space of this construction. There are special

Systematics of the α′ expansion in F-theory [PDF]
Journal of High Energy Physics, 2021 Abstract Extracting reliable low-energy information from string compactifications notoriously requires a detailed understanding of the UV sensitivity of the corresponding effective field theories. Despite past efforts in computing perturbative string corrections to the tree-level action, neither a systematic approach nor a unified ...

High U(1) charges in type IIB models and their F-theory lift [PDF]
Journal of High Energy Physics, 2018 A bstractWe construct models with U(1) gauge group and matter with charges up to 6, in the context of type IIB compactifications. We show explicitly that models with charges up to 4 can be derived from corresponding models in F-theory by applying the Sen

The footprint of F-theory at the LHC [PDF]
Journal of High Energy Physics, 2009 Recent work has shown that compactifications of F-theory provide a potentially attractive phenomenological scenario. The low energy characteristics of F-theory GUTs consist of a deformation away from a minimal gauge mediation scenario with a high messenger scale. The soft scalar masses of the theory are all shifted by a stringy effect which survives to

F-theory at constant coupling [PDF]
Physics Letters B, 1996 The subspace of the moduli space of F-theory on K3 over which the coupling remains constant develops new branches at special values of this coupling. These values correspond to fixed points under the SL(2,Z) duality group of the type IIB string. The branches contain points where K3 degenerates to orbifolds of the four-torus by Z_3,Z_4 and Z_6.

Tate’s algorithm and F-theory [PDF]
Journal of High Energy Physics, 2011 The "Tate forms" for elliptically fibered Calabi-Yau manifolds are reconsidered in order to determine their general validity. We point out that there were some implicit assumptions made in the original derivation of these "Tate forms" from the Tate algorithm.
