Decomposition of Some Pointed Hopf Algebras given by the Canonical Nakayama Automorphism
Every finite dimensional Hopf algebra is a Frobenius algebra, with Frobenius homomorphism given by an integral. The Nakayama automorphism determined by it yields a decomposition with degrees in a cyclic group. For a family of pointed Hopf algebras, we determine necessary and sufficient conditions for this decomposition to be strongly graded.

My research interests primarily lie in the fields of networks and distributed systems and span the areas of smart grid management models, optimal flow controls, traffic engineering, load balancing, fault-tolerant systems, and circuit and systems. The goal of my research is to develop breakthrough technologies that radically improve the performance of those network systems by delving into each s...
متن کاملSkew quantum Murnaghan-Nakayama rule
In this extended abstract, we extend recent results of Assaf and McNamara, the skew Pieri rule and the skew Murnaghan-Nakayama rule, to a more general identity, which gives an elegant expansion of the product of a skew Schur function with a quantum power sum function in terms of skew Schur functions. We give two proofs, one completely bijective in the spirit of Assaf-McNamara’s original proof, ...
متن کاملNakayama , Shimojo , and Ramachandran ' s 1990 paper
Surfaces revisited The target paper reviewed in this article was titled `̀ Transparency: relation to depth, subjective contours, luminance, and neon colour spreading'' coauthored by K Nakayama, S Shimojo, and V S Ramachandran, published in 1990. This paper, one of the first in a series on surface perception, examined how in untextured stereograms, local disparity and luminance contrast can drast...
متن کاملSkew Calabi-yau Algebras and Homological Identities
A skew Calabi-Yau algebra is a generalization of a Calabi-Yau algebra which allows for a non-trivial Nakayama automorphism. We prove three homological identities about the Nakayama automorphism and give several applications. The identities we prove show (i) how the Nakayama automorphism of a smash product algebra A#H is related to the Nakayama automorphisms of a graded skew Calabi-Yau algebra A...
