We consider the Bayesian methods for solving inverse problems in function space.The often used Gaussian processes prior often has difficulty in dealing with functions with discontinuities.

We consider an inverse problem where the model is a time-fractional diffusion.In particular we consider the problem where the Caputo fractional derivative order α is not known.

Bounds on the Size of An Inclusion Using the Translation Method for Twodimensional Complex Conductiv
The size estimation problem in electrical impedance tomography is considered when the conductivity is a complex number and the body is twodimensional.

Generalized Empirical Likelihood Inference for Longitudinal Data with Missing Response Variables and
Incomplete longitudinal data often arise in many areas.In this article,we consider longitudinal partial linear models when the response variable is missing probability depending on the covariate that

Integrable Self-adaptive Moving Mesh Methods for A Class of NonlinearWave Equations with Hodograph T
In the present talk,I will firstly report our recent work on integrable discretizations for a class of soliton equations with hodograph transformations such as the Camassa-Holm,the short-pulse(SP),the

Totally Conservative Integrator for Integrable Hamiltonian Systems and Its Generalization to Holonom
Some holonomic constrained systems have the Hamiltonian,which is the sum of the Hamiltonian of an integrable system,St(a)ckel system and terms including a Lagrange multiplier and holonomic constraint.
