Giant graviton interactions and M2-branes ending on multiple M5-branes

AbstractWe study splitting and joining interactions of giant gravitons with angular momenta N 1/2 ≪ J ≪ N in the type IIB string theory on AdS5 × S5 by describing them as instantons in the tiny graviton matrix model introduced by Sheikh-Jabbari. At large J the instanton equation can be mapped to the four-dimensional Laplace equation and the Coulomb potential for m point charges...

ABJ theory in the higher spin limit

We study the conjecture made by Chang, Minwalla, Sharma, and Yin on the duality between the \( \mathcal{N}=6 \) Vasiliev higher spin theory on AdS4 and the \( \mathcal{N}=6 \) Chern-Simons-matter theory, so-called ABJ theory, with gauge group U(N) × U(N + M). Building on our earlier results on the ABJ partition function, we develop the systematic 1/M expansion, corresponding to...

The partition function of ABJ theory

We study the partition function of the $\mathcal {N}=6$ supersymmetric U(N1)k × U(N2)−k Chern–Simons-matter (CSM) theory, also known as the ABJ theory. For this purpose, we first compute the partition function of the U(N1) × U(N2) lens space matrix model exactly. The result can be expressed as a product of the q-deformed Barnes G-function and a generalization of the multiple q...

Epidemiology of vampire bat-transmitted rabies virus in Goiás, central Brazil: re-evaluation based on G-L intergenic region

Background Vampire bat related rabies harms both livestock industry and public health sector in central Brazil. The geographical distributions of vampire bat-transmitted rabies virus variants are delimited by mountain chains. These findings were elucidated by analyzing a high conserved nucleoprotein gene. This study aims to elucidate the detailed epidemiological characters of...

Topological Matrix Model

Starting from the primal principle based on the noncommutative nature of (9+1)-dimensional spacetime, we construct a topologically twisted version of the supersymmetric reduced model with a certain modification. Our formulation automatically provides extra (1+1)-dimensions, thereby the dimension of spacetime is promoted to 10 + 2. With a suitable gauge choice, we can reduce the...

Molecular and geographic analyses of vampire bat-transmitted cattle rabies in central Brazil

Background Vampire bats are important rabies virus vectors, causing critical problems in both the livestock industry and public health sector in Latin America. In order to assess the epidemiological characteristics of vampire bat-transmitted rabies, the authors conducted phylogenetic and geographical analyses using sequence data of a large number of cattle rabies isolates...
