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

Algorithmic universality in F-theory compactifications [PDF]
, 2017 We study universality of geometric gauge sectors in the string landscape in the context of F-theory compactifications. A finite time construction algorithm is presented for $\frac43 \times 2.96 \times 10^{755}$ F-theory geometries that are connected by a

F-theory on quotient threefolds with (2,0) discrete superconformal matter [PDF]
Journal of High Energy Physics, 2018 A bstractWe explore 6-dimensional compactifications of F-theory exhibiting (2, 0) superconformal theories coupled to gravity that include discretely charged superconformal matter.

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.

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

Journal of High Energy Physics, 2013 F-theory is a non-perturbative formulation of type IIB superstring theory which allows for the decoupling of gravity and for the formulation of GUT theories based on the gauge group E6. In this paper we explore F-theory models in which the low energy supersymmetric theory contains the particle content of three 27 dimensional representations of the ...

Scanning the skeleton of the 4D F-theory landscape [PDF]
, 2017 A bstractUsing a one-way Monte Carlo algorithm from several different starting points, we get an approximation to the distribution of toric threefold bases that can be used in four-dimensional F-theory compactification.

F-theory from fundamental five-branes
Journal of High Energy Physics, 2021 We describe the worldvolume for the bosonic sector of the lower-dimensional F-theory that embeds 4D, N=1 M-theory and the 3D Type II superstring. The worldvolume (5-brane) theory is that of a single 6D gauge 2-form X MN (σ P ) whose field strength is ...
