Cluster algebras and continued fractions (2017)
Journal Article
Çanakçı, İ., & Schiffler, R. (2018). Cluster algebras and continued fractions. Compositio Mathematica, 154(03), 565-593. https://doi.org/10.1112/s0010437x17007631

We establish a combinatorial realization of continued fractions as quotients of cardinalities of sets. These sets are sets of perfect matchings of certain graphs, the snake graphs, that appear naturally in the theory of cluster algebras. To a continu...

Continuous dependence on modelling for temperature-dependent bidispersive flow (2017)
Journal Article
Franchi, F., Nibbi, R., & Straughan, B. (2017). Continuous dependence on modelling for temperature-dependent bidispersive flow. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 473(2208), Article 20170485. https://doi.org/10.1098/rspa.2017.0485

We consider a model for flow in a porous medium which has a double porosity structure. There is the usual porosity herein called macro porosity, but in addition, we allow for a porosity due to cracks or fissures in the solid skeleton. The cracks give...

On the rate of convergence to equilibrium for the linear Boltzmann equation with soft potentials (2017)
Journal Article
Cañizo, J. A., Einav, A., & Lods, B. (2018). On the rate of convergence to equilibrium for the linear Boltzmann equation with soft potentials. Journal of Mathematical Analysis and Applications, 462(1), 801-839. https://doi.org/10.1016/j.jmaa.2017.12.052

In this work we present several quantitative results of convergence to equilibrium for the linear Boltzmann operator with soft potentials under Grad's angular cut-off assumption. This is done by an adaptation of the famous entropy method and its vari... Read More about On the rate of convergence to equilibrium for the linear Boltzmann equation with soft potentials.

Elastic 3D shape analysis using square-root normal field representation (2017)
Presentation / Conference Contribution
Laga, H., Jermyn, I. H., Kurtek, S., & Srivastava, A. (2017, December). Elastic 3D shape analysis using square-root normal field representation. Presented at 56th IEEE Conference on Decision and Control., Melbourne, Australia

Shape is an important physical property of natural and man-made 3D objects that characterizes their external appearances. Understanding differences between shapes, and modeling the variability within and across shape classes, hereinafter referred to...

Marginal and joint reliability importance based on survival signature (2017)
Journal Article
Eryilmaz, S., Coolen, F., & Coolen-Maturi, T. (2018). Marginal and joint reliability importance based on survival signature. Reliability Engineering & System Safety, 172, 118-128. https://doi.org/10.1016/j.ress.2017.12.002

Marginal and joint reliability importance measures have been found to be useful in optimal system design. Various importance measures have been defined and studied for a variety of system models. The results in the literature are mostly based on the... Read More about Marginal and joint reliability importance based on survival signature.

Exceptional N=3 theories (2017)
Journal Article
García-Etxebarria, I., & Regalado, D. (2017). Exceptional N=3 theories. Journal of High Energy Physics, 12, Article 042. https://doi.org/10.1007/jhep12%282017%29042

We present a new construction of four dimensional N = 3 theories, given by M5 branes wrapping a T 2 in an M-theory U-fold background. The resulting setup generalizes the one used in the usual class S construction of four dimensional theories by using... Read More about Exceptional N=3 theories.

Reconfinement and loss of stability in jets from active galactic nuclei (2017)
Journal Article
Gourgouliatos, K. N., & Komissarov, S. S. (2018). Reconfinement and loss of stability in jets from active galactic nuclei. Nature Astronomy, 2(2), 161-171. https://doi.org/10.1038/s41550-017-0338-3

Jets powered by active galactic nuclei appear impressively stable compared with their terrestrial and laboratory counterparts—they can be traced from their origin to distances exceeding their injection radius by up to a billion times. However, some l... Read More about Reconfinement and loss of stability in jets from active galactic nuclei.

Diffusion in inhomogeneous media (2017)
Journal Article
Donos, A., Gauntlett, J. P., & Ziogas, V. (2017). Diffusion in inhomogeneous media. Physical Review D, 96(12), Article 125003. https://doi.org/10.1103/physrevd.96.125003

We consider the transport of conserved charges in spatially inhomogeneous quantum systems with a discrete lattice symmetry. We analyze the retarded two-point functions involving the charges and the associated currents at long wavelengths, compared to... Read More about Diffusion in inhomogeneous media.

The Mechanism for the Energy Buildup Driving Solar Eruptive Events (2017)
Journal Article

The underlying origin of solar eruptive events (SEEs), ranging from giant coronal mass ejections to small coronal-hole jets, is that the lowest-lying magnetic flux in the Sun's corona undergoes continual buildup of stress and free energy. This magnet... Read More about The Mechanism for the Energy Buildup Driving Solar Eruptive Events.

Classification of compactified su(Nc) gauge theories with fermions in all representations (2017)

We classify su(N c ) gauge theories on R3×S1 with massless fermions in higher representations obeying periodic boundary conditions along S1. In particular, we single out the class of theories that is asymptotically free and weakly coupled in the infr...
