Curvature divergences and gravity decoupling in Calabi-Yau rigid limits

Journal of High Energy Physics
Four-dimensional N $$ \mathcal{N} $$ = 2 supergravity theories become rigid in gravity-decoupling limits. We study this effect for type II string compactifications on general Calabi-Yau manifolds, focusing on vector-multiplet trajectories whose endpoints

A geometric simulation theorem on direct products of finitely generated groups

Discrete Analysis, 2019
A geometric simulation theorem on direct products of finitely generated groups, Discrete Analysis 2019:9, 25 pp. In 1961, the mathematician and philosopher Hao Wang introduced the notion that we now call a _Wang tiling_ of $\mathbb Z^2$.

A Finite Element Analysis for the Damaged Rotating Composite Blade

Al-Khawarizmi Engineering Journal, 2019
In this paper, the finite element method is used to study the dynamic behavior of the damaged rotating composite blade. Three dimensional, finite element programs were developed using a nine node laminated shell as a discretization element for the blade ...

Vibroacoustic Response of a Disc-Type Underwater Glider During Its Entry into Water

Journal of Marine Science and Engineering
Underwater gliders are extensively employed in oceanographic observation and detection. The structural characteristics of thin-wall shells are more susceptible to vibrations from internal mechanical components; this noise emission becomes more complex ...

Bounds for OPE coefficients on the Regge trajectory

Journal of High Energy Physics, 2017
We consider the Regge limit of the CFT correlation functions JJOO $$ \left\langle \mathcal{JJOO}\right\rangle $$ and T T O O $$ \left\langle TT\mathcal{O}\mathcal{O}\right\rangle $$ , where J $$ \mathcal{J} $$ is a vector current, T is the stress tensor ...
