Isogeometric analysis (IGA) has been recently developed to build a bridge between geometric computer-aided design and PDE analysis. In IGA, spline functions used for geometric domain descriptions are also used to discretize PDE problems on such...

Consider all shifts of finite type constrained by a condition on the forbidden set, e.g. only allowing a single forbidden word of fixed length. Which such shifts have the minimum/maximum possible entropy? Among all binary shifts forbidding a single...

Habitat loss is a key component driving decreases in biodiversity and the extinction of species worldwide. Of particular concern is human-driven habitat loss, primarily through agriculture, resource extraction, and urbanization. In this talk, I will...

Elliptic curve isogeny path finding has many applications in number theory and cryptography. For supersingular curves, this problem is known to be easy when one small endomorphism or the entire endomorphism ring are known. Unfortunately, computing...

Motivated by an application in the routing of technicians at a French public utility, we introduce a highly efficient heuristic together with a branch-price-and-cut algorithm for the doubly open park-and-loop routing problem. This problem is an...

The eccentricity matrix ε(G) of a connected graph G is obtained from the distance matrix of G by keeping the largest nonzero entries in each row and each column, and leaving zeros in the remaining ones. The eigenvalues of ε(G) are the ε-eigenvalues...

A revolution has been underway in wave physics in recent years based around concepts of resonance and microstructured media often coupled with periodicity. This has resulted in materials known as metamaterials that have, for instance, negative...

If a tricky devil challenged you to complete a Sudoku puzzle of their design, what restrictions could you place on their design to guarantee it was impossible for them to thwart your attempts? More specifically, if you could dictate exactly how many...

Our introduction of the notion of a non-linear Kantorovich operator was motivated by the celebrated duality in the mass transport problem, hence the name. In retrospect, we realized that they -and their iterates- were omnipresent in several branches...

It is well-known in quantum information theory that a positive operator valued measure (POVM) is the most general kind of quantum measurement. A quantum probability is a normalised POVM, namely a function on certain subsets of a (locally compact and...
