Redrawing the 2012 map of the Maryland congressional districts [PDF]

open access: yesarXiv, 2023
Gerrymandering is the practice of drawing biased electoral maps that manipulate the voter population to gain an advantage. The most recent time gerrymandering became an issue was 2019 when the U.S. Federal Supreme Court decided that the court does not have the authority to dictate how to draw the district map and state legislators are the ones who ...

Differences of weighted composition operators between the Fock spaces [PDF]

open access: yesarXiv, 2017
We study some important topological properties such as boundedness, compactness and essential norm of differences of weighted composition operators between Fock ...

Taming the Gerrymander--Statistical Physics Approach to Political Districting Problem [PDF]

open access: yes, 2005
The Political Districting Problem is mapped to a $q$-state Potts model in which the constraints can be written as interactions between sites or external fields acting on the system. Districting into $q$ voter districts is equivalent to finding the ground state of this $q$-state Potts model.

District-Fair Participatory Budgeting [PDF]

open access: yesarXiv, 2021
Participatory budgeting is a method used by city governments to select public projects to fund based on residents' votes. Many cities use participatory budgeting at a district level. Typically, a budget is divided among districts proportionally to their population, and each district holds an election over local projects and then uses its budget to fund

District Level Analysis of Urbanization from Rural-to-Urban Migration in the Rajasthan State [PDF]

open access: yesarXiv, 2009
Migration has various dimensions; urbanization due to migration is one of them. In Rajasthan State, district level analysis of urbanization due to migrants shows trend invariably for all districts of the state, though the contribution in urbanization by migrants varies from district to district.

A Refined Complexity Analysis of Fair Districting over Graphs [PDF]

open access: yesarXiv, 2021
We study the NP-hard Fair Connected Districting problem recently proposed by Stoica et al. [AAMAS 2020]: Partition a vertex-colored graph into k connected components (subsequently referred to as districts) so that in every district the most frequent color occurs at most a given number of times more often than the second most frequent color.

Identification of nitrate sources using hydrogeochemical and stable isotope in the aquifer, Amphoe Kaeng Khoi, Changwat Saraburi

open access: yes
A long time agricultural activities result in the NO3- contamination in groundwater in Thailand. The objectives of this research were: to investigate hydrogeochemical and hydrogeological characteristics, to assess nitrate concentration in groundwater and

On the SU(2,1) representation space of the Brieskorn homology spheres [PDF]

open access: yesJ. Math. Sci. Univ. Tokyo 14 (2007), no. 4, 499--510, 2008
In this paper, we give a parameterization of the SU(2,1) representation space of the Brieskorn homology spheres using the trace coordinates. As applications, we give an example which shows that the orbifold Toledo invariant in \cite{krebs} does not distinguish the connected components of the PU(2,1) representation space.

Baseline Characterization of Tad Fa Watershed, Khon Kaen Province, Northeast Thailand [PDF]

open access: yes, 2012
Agriculture is the main occupation in Thailand and it plays an important role in the economic development of the country. Thailand is located in the tropical monsoon climate region where the amount of rainfall is high but shortage of water occurs even

On the Burns-Epstein invariants of spherical CR 3-manifolds [PDF]

open access: yesarXiv, 2008
In this paper we develop a method to compute the Burns-Epstein invariant of a spherical CR homology sphere, up to an integer, from its holonomy representation. As application, we give a formula for the Burns-Epstein invariant, modulo an integer, of a spherical CR structure on a Seifert fibered homology sphere in terms of its holonomy representation.
