Regular Flips in mptopcom
Lars Kastner
A triangulation of a point configuration is regular if it can be given by a height function, that is every point gets lifted to a certain height and projecting the lower convex hul…
Design of Polynomial-delay Enumeration Algorithms in Transitive Systems
Kazuya Haraguchi, Hiroshi Nagamochi
In this paper, as a new notion, we define a transitive system to be a set system on a finite set of elements such that every three sets $X,Y,Z\…
Polynomial-delay Enumeration Algorithms in Set Systems
Kazuya Haraguchi, Hiroshi Nagamochi
We consider a set system on a finite set of elements, where we call a set a component. We assume that two oracles $\mathrm{…
Contract Design with Costly Convex Self-Control
Yusufcan Masatlioglu, Daisuke Nakajima, Emre Ozdenoren
In this note, we consider the pricing problem of a profit-maximizing monopolist who faces naive consumers with convex self-control preferences.
Maximum Weighted Matching with Few Edge Crossings for 2-Layered Bipartite Graph
Kazuya Haraguchi, Kotaro Torii, Motomu Endo
Let c denote a non-negative constant. Suppose that we are given an edge-weighted bipartite graph G=(V,E) with its 2-layered drawing and a family X of intersecting edge pairs. We co…
Lauricella's with finite irreducible monodromy group
Yoshiaki Goto
We study the conditions under which the monodromy group for Lauricella's hypergeometric function is finite irreducible. We give the conditions in terms of the param…
Picard-Vessiot groups of Lauricella's hypergeometric systems and Calabi-Yau varieties arising integral representations
Yoshiaki Goto, Kenji Koike
We study the Zariski closure of the monodromy group of Lauricella's hypergeometric function . If the identity component acts irreducibly, then…
Momentum-Space Renormalization Group Transformation in Bayesian Image Modeling by Gaussian Graphical Model
Kazuyuki Tanaka, Masamichi Nakamura, Shun Kataoka +2
A new Bayesian modeling method is proposed by combining the maximization of the marginal likelihood with a momentum-space renormalization group transformation for Gaussian graphica…
Holonomic Gradient Method for Two Way Contingency Tables
Yoshihito Tachibana, Yoshiaki Goto, Tamio Koyama +1
The holonomic gradient method gives an algorithm to efficiently and accurately evaluate normalizing constants and their derivatives. We apply the holonomic gradient method in the c…
Linear-Time Algorithm in Bayesian Image Denoising based on Gaussian Markov Random Field
Muneki Yasuda, Junpei Watanabe, Shun Kataoka +1
In this paper, we consider Bayesian image denoising based on a Gaussian Markov random field (GMRF) model, for which we propose an new algorithm. Our method can solve Bayesian image…
Irreducibility of the monodromy representation of Lauricella's
Yoshiaki Goto, Keiji Matsumoto
Let be the hypergeometric system of differential equations satisfied by Lauricella's hypergeometric series of variables. We show that the monodromy representation o…
Zeros of the first derivative of Dirichlet -functions
Hirotaka Akatsuka, Ade Irma Suriajaya
Yıldırım has classified zeros of the derivatives of Dirichlet -functions into trivial zeros, nontrivial zeros and vagrant zeros. In this paper we remove the possibility of vagra…
Macroeconomic Forecasting and Variable Selection with a Very Large Number of Predictors: A Penalized Regression Approach
Yoshimasa Uematsu, Shinya Tanaka
This paper studies macroeconomic forecasting and variable selection using a folded-concave penalized regression with a very large number of predictors. The penalized regression app…
On A Generalization of "Eight Blocks to Madness"
Kazuya Haraguchi
We consider a puzzle such that a set of colored cubes is given as an instance. Each cube has unit length on each edge and its surface is colored so that what we call the Surface Co…
An Efficient Local Search for Partial Latin Square Extension Problem
Kazuya Haraguchi
A partial Latin square (PLS) is a partial assignment of n symbols to an nxn grid such that, in each row and in each column, each symbol appears at most once. The partial Latin squa…
A tight upper bound on the (2,1)-total labeling number of outerplanar graphs
Toru Hasunuma, Toshimasa Ishii, Hirotaka Ono +1
A -total labeling of a graph is an assignment from the vertex set and the edge set to the set of nonnegative integers such that $|f(x)-…
A linear time algorithm for L(2,1)-labeling of trees
Toru Hasunuma, Toshimasa Ishii, Hirotaka Ono +1
An L(2,1)-labeling of a graph is an assignment from the vertex set to the set of nonnegative integers such that if and are adjacent and $|…
Quasi-self-similar evolution of the two-point correlation function: strongly nonlinear regime in Omega_0 < 1 universes
Tatsushi Suginohara, Atsushi Taruya, Yasushi Suto
The well-known self-similar solution for the two-point correlation function of the density field is valid only in an Einstein-de Sitter universe. We attempt to extend the solution…
