In this paper, we introduce the notation of bi-shift of biprojections in subfactor theory to unimodular Kac algebras. We characterize the minimizers of Hirschman-Beckner uncertainty principle and Donoho-Stark uncertainty principle for unimodular Kac algebras with biprojections and prove Hardy's uncertainty principle in terms of minimizers.

Quantum smooth uncertainty principles for von Neumann bi-algebras
Various smooth uncertainty principles on von Neumann bi-algebras are proved, which unify numbers of uncertainty Principles on quantum symmetries, such as subfactors, and fusion bi- algebrs etc, studied in quantum Fourier analysis.
Strong Subadditivity Inequality and Entropic Uncertainty Relations
We prove a generalization of the strong-subadditivity (SSA) inequality in the context of finite dimensional von Neumann algebras. Our generalized SSA inequality subsumes various entropic uncertainty
Galois Correspondence and Fourier Analysis on Local Discrete Subfactors
Discrete subfactors include a particular class of infinite index subfactors and all finite index ones. A discrete subfactor is called local when it is braided and it fulfills a commutativity

We study lattice operations on the set of idempotent states on a locally compact quantum group corresponding to the operations of intersection of compact subgroups and forming the subgroup generated

The uncertainty principle has been established within the framework of locally compact quantum groups in recent years. This paper demonstrates that entropic uncertainty relations can be strengthened
Quantum Fourier analysis
This paper introduces this mathematical subject, shows how it can solve some theoretical problems, and gives some applications to quantum physics with bounds on entropy and the analysis of quantum entanglement.

Noncommutative Uncertainty Principles
The minimizers of the uncertainty principles are characterized and then Hardy's uncertainty principle is proved by using minimizers, which proves that the minimizer is uniquely determined by the supports of itself and its Fourier transform.
Locally compact quantum groups
These lecture notes are intended as an introduction to the theory of locally compact quantum groups that are studied in the framework of operator algebras, i.e. C*-algebras and von Neumann algebras.
An uncertainty principle for unimodular quantum groups
We present a generalization of Hirschman's entropic uncertainty principle for locally compact Abelian groups to unimodular locally compact quantum groups. As a corollary, we strengthen a well-known
Finite index subfactors and Hopf algebra crossed products
We show that if N ⊆ M ⊆ L ⊆ K is a Jones's tower of type II 1 factors satisfying [M: N] < ∞, N' ∩ M = CI, N' ∩ K a factor, then M' ∩ K bears a natural Hopf *-algebra structure and there is an action
Abstract We classify all functions on a locally compact, abelian group giving equality in an entropy inequality generalizing the Heisenberg Uncertainty Principle. In particular, for functions on a
Irreducible Inclusions of Factors, Multiplicative Unitaries, and Kac Algebras
Abstract From an irreducible depth 2 inclusion of factors, verifying a regularity condition, we construct a multiplicative unitary, and an action, at every level of the canonical tower constructed
Young's inequality for locally compact quantum groups
In this paper, we generalize Young's inequality for locally compact quantum groups and obtain some results for extremal pairs of Young's inequality and extremal functions of Hausdorff-Young
Uncertainty principles for compact groups
We establish an operator-theoretic uncertainty principle over arbitrary compact groups, generalizing several previous results. As a consequence, we show that if f is in L^2(G), then the product of
Duality Theorems for Kac Algebras and Locally Compact Groups
In that chapter, we obtain a duality theorem for Kac algebras, namely that the bidual Kac algebra is isomorphic to the original Kac algebra (4.1.1). From that, we can successively deduce that the
Locally compact quantum groups
Quantum groups can be viewed as deformations/liberations of classical locally compact groups. Around the year 2000 a thorough definition of a locally compact quantum group was given by Kustermans and
