Abstract: We will introduce the definition of homology of a small category with functor coefficients and then compare two different homologies when we take the category of a simpli
Character Varieties of surfaces as completely integrable systems
Abstract: It is known that the trace functions of a maximal set of disjoint simple closed curves on a closed surface make its SU(2)-character variety into an (almost) completely in
Adiabatic quantum computing: equivalence with quantum computing
Abstract: The adiabatic quantum computing (AQC) was originally introduced to solve optimization problems by constructing two Hamiltonian operators where the first one is easy to prepare and the sec
The Bonahon Metric and Topology
Abstract: In his book “Low-Dimensional Geometry: From Euclidean Spaces to Hyperbolic Knots”, Francis
Mochizuki's quandle 3-cocycle invariant of links S^3 is one of the Dijkgraaf-Witten invariants
Abstract: Let p be an odd prime, and \phi the Mochizuki 3-cocycle of "the
dihedral quandle" of order p. Using the 3-cocycle, Carter-Kamada-Saito
Jointly with Math Colloquium and Applied Math Seminar: Topological Quantum Computation
Abstract: Quantum computing models have the potential to perform tasks such as factoring integers and simulating quantum physics exponentially faster than any known classical algor
Modified right-angled Artin groups.
Abstract: The family of right-angled Artin groups (RAAGs) interpolates between the family of finitely generated free groups on one hand and the family of finitely generated free abelian groups on t
Adiabatic quantum computing: application to NP-hard problems
Abstract: Adiabatic quantum computing (AQC) have been shown to be a useful tool for approximating optimization problems. We show an experimental study of the AQC applied to the MaxSat problem.
Homology of Distributive Lattice
Abstract: While homology theory of associative structures, such as groups and rings, was extensively studied in the past, beginning with the work of Hopf, Eilenberg, and Hochschild, homology of non
Adiabatic quantum computing: the construction of Hamiltonian operators
Abstract: Adiabatic Quantum Computing (AQC) has been applied to solve optimization problems.
