The Canadian Conference on Computational Geometry (CCCG) is a forum to disseminate and discuss theoretical and applied results in discrete and computational geometry. Computational geometry is concerned with the design of efficient algorithms, the development of software, and the study of the mathematical foundations of computational problems whose formulation involves geometric constraints. The field is motivated by problems from a broad range of application areas, as diverse as computer graphics and animation, computer vision, computer-aided design and manufacturing, geographic information…

Science Atlantic Mathematics, Statistics, and Computer Science Conference
The Science Atlantic Mathematics, Statistics, and Computer Science Conference is held each October and provides an opportunity for students to present their research and to learn about other undergraduate research projects across the region in a supportive and inclusive environment. Undergraduate students are also able to participate in team-based mathematics and programming competitions. The conference additionally provides a valuable opportunity for undergraduate students to meet potential graduate supervisors, and is the only venue for faculty members from across Atlantic Canada…

Addressing graphs and hypergraphs In 1970s, Ron Graham and Henry Pollak introduced the notion of graph addressing which is a labeling of the vertices of an undirected graph by words of the same length over the alphabet {0,1,*} such that the distance between any two vertices equals the number of positions in their labels/addresses where one vertex has a 0 and the other one has a 1. The minimum of length of such words has been investigated by various people…

The 19th Seminar on Commutative Algebra and related topics
Every year the school of mathematics of IPM-Tehran organizes a seminar and workshop to introduce the research topics in the main streams of "Algebraic Geometry, Commutative algebra and Combinatorial commutative algebra" to young researchers and PhD students, and encourage them to collaborate in teams led by well-known mathematicians in this area. This year we have paid special attention to inviting regional speakers, as well as international leaders. Our list of speakers highlights female mathematicians, and the areas represented are those…

An Unsupervised Framework for Comparing Graph Embeddings The goal of many machine learning applications is to make predictions or discover new patterns using graph-structured data as feature information. In order to extract useful structural information from graphs, one might want to try to embed it in a geometric space by assigning coordinates to each node such that nearby nodes are more likely to share an edge than those far from each other. There are many embedding algorithms (based on techniques…

Title: Energy Minimizing Surface Tension Configurations for Microparticles Abstract: An important area of microfluidics is the creation and manipulation of small droplets. This is commonly done using microchannels or electrowetting. Recently a new method is proposed to create templated droplets using amphiphilic microparticles. These particles are observed to hold nearly equal volumes of aqueous liquid when dispersed in an oil–water mixture. However a theory for this behavior is lacking. In this paper, we present a mathematical model based on minimizing the…

Conditions for perfect matchings in random sparse bipartite graphs Given a uniformly random sparse matrix A, with specified number of nonzero entries in columns and rows, we determine when A has full row rank over a finite field. As a corollary, by considering A as the adjacency matrix of a bipartite graph, our result determines the conditions for the existence of a perfect matching in various models of random sparse bipartite graphs. We will explore some useful insight from statistical…

Title: Eigenfunction restriction estimates on curves with nonvanishing geodesic curvatures Abstract: Studying eigenfunctions of the Laplace-Beltrami operator on compact Riemannian manifolds (without boundary) is one of the interesting topics in Harmonic Analysis. One way to study them is to consider the L^p estimates of the eigenfunctions restricted to submanifolds. In this talk, we briefly summarize previous results and would like to talk about the logarithmic improved analogue for the restriction to curves with nonvanishing geodesic curvatures, in the presence of nonpositive…
