the decomposition $gamma=bh$ of a group $gamma$ into a subset $b$ and a subgroup $h$ of $gamma$ induces, under general conditions, a group-like structure for $b$, known as a gyrogroup. the famous concrete realization of a gyrogroup, which motivated the emergence of gyrogroups into the mainstream, is the space of all relativistically admissible velocities along with a binary operation given by t...

blackberry diversity is high in iran due to its wild and natural populations especially in south of caspian sea. however it has not been investigated before. the goal of this work was to evaluate some wild populations of black berry in mazandaran province of iran. at first, region and then location of blackberries plants identified and the traits of leaf, stem, spin, flower, fruit quantity and ...

We investigate dimerized quantum spin systems using the functional renormalization group approach proposed by Krieg and Kopietz [Phys. Rev. B 99, 060403(R) (2019)] which directly focuses on physical correlation functions avoids representation of spins in terms fermionic or bosonic auxiliary operators. Starting from decoupled dimers as initial condition for flow equations, we obtain spectrum tri...
