Index Theory for Symplectic Matrix Paths with Applications

The fundamental solution of a linear Hamiltonian system is a symplectic matrix path starting from the identity matrix. The study of the index theory of symplectic paths aims at understanding properties of solutions of nonlinear Hamiltonian systems vi more››

Ptolemy's theorem and extensions

Ptolemy's theorem is where serious trigonometry starts, although it is chords of circles rather than right triangles which are the building blocks. Ptolemy's theorem deals with cyclic quadrilaterals, their sides and the diagonals. In Ptolemy's book, more››

Learn from Thy Neighbour: Parallel-Chain Adaptive MCMC

A considerable amount of effort has been recently invested in developing a comprehensive theory for adaptive MCMC. In comparison, there are fewer adaptive algorithms designed for practical situations. I will review some of the theoretical approaches more››

Particle Patterns in Dissipative Systems

Particle patterns mean any spatially localized structures sustained by the balance between inflow and outflow of energy/material, which arise in the form of chemical blobs, discharge patterns, morphological spots, or binary convection cells. These ar more››

Effective equidistribution of Hecke eigenvalues

For a fixed prime p, we consider the space S(N,k) of cusp forms of weight k and level N, with N coprime to p. In 1995, J.-P. Serre proved the existence of a measure up with respect to which the eigenvalues of the pth Hecke operator acting on S(N,k) a more››

The stakes of capture-recapture models with state uncertainty

The development of the use of CR multistate models is a major feature of the last 5 years. However, concerns have rightfully appeared about uncertainty in state assignment. I examine situations where uncertainties seem to be intrinsic such as with more››

Error Estimates of Discontinuous Galerkin Methods for Elliptic Problems

We introduce the discontinuous Galerkin methods for elliptic problems, which are closely related to the penalty methods, to establish the optimal error estimates in the energy and L^2 norms of the discontinuous Galerkin methods, and to verify the more››

Geometric approaches to parameter estimation for differential equations.

Parameter estimation for differential equations is a fundamental problem, but work in this area is incomplete. One difficulty is the presence of local minima which trap optimization algorithms, resulting in poor fits. Incorporating geometric featu more››

The Adams-Riemann-Roch theorem and applications

We shall formulate the Adams-Riemann-Roch theorem, which is a refinement of the Grothendieck-Riemann-Roch theorem taking into account torsion. We shall apply the theorem to the de Rham complex. This will lead to a conjecture on the torsion of the more››

Composition of Time-Consistent Dynamic Monetary Risk Measures in Discrete Time

In discrete time, every time-consistent dynamic monetary risk measure can be written as a composition of one-step risk measures. We exploit this structure to give new dual representation results for time-consistent convex monetary risk measures in more››

Models of Initiation and Propagation of Dendritic Spikes in Hippocampal CA1 Pyramidal Neurons

In computational models of hippocampal CA1 pyramidal neurons with active dendrites, distal synaptic inputs trigger dendritic spikes, but in many cases these spikes do not propagate reliably to the soma to produce output action potentials in the ax more››
