Nakayama functor for coalgebras and a categorical perspective of the integral theory for Hopf algebras

Kenichi Shimizu

We review basic properties of the Nakayama functor for coalgebras and introduce a number of applications to tensor categories. We also give equivalent conditions for a coquasi-bial…

Pointed Hopf superalgebras of dimension up to 10

Taiki Shibata, Kenichi Shimizu, Ryota Wakao

By utilizing the technique introduced in our previous work to construct Hopf superalgebras by an inverse procedure of the Radford-Majid bosonization, we classify non-semisimple poi…

Nakayama functor for monads on finite abelian categories

Kenichi Shimizu

If is a finite abelian category and is a linear right exact monad on , then the category $\mathbf{T}\mbox{-mod}$ of -modules is…

Semiparametric Bayesian Estimation of Dynamic Discrete Choice Models

Andriy Norets, Kenichi Shimizu

We propose a tractable semiparametric estimation method for structural dynamic discrete choice models. The distribution of additive utility shocks in the proposed framework is mode…

Asymptotic properties of Bayesian inference in linear regression with a structural break

Kenichi Shimizu

This paper studies large sample properties of a Bayesian approach to inference about slope parameters in linear regression models with a structural break. In contrast to the co…

Bayesian Approaches to Shrinkage and Sparse Estimation

Dimitris Korobilis, Kenichi Shimizu

In all areas of human knowledge, datasets are increasing in both size and complexity, creating the need for richer statistical models. This trend is also true for economic data, wh…
