The Use of Block Methods for Solving Differential Problems


Prof. Higinio Ramos, Department of Applied Mathematics, University of Salamanca, Salamanca, Spain. Email: 

Block methods have been used lately for approximating different kind of differential problems, although they are more recent than classical methods as linear multistep methods or Runge-Kutta ones. The oldest known reference about these methods goes back to William Edmund Milne, in a work dated at 1953 (Numerical Solution of Differential Equations, John Wiley and Sons).

The block methods consist of a series of formulas that make possible to approximate the solution of a differential problem at more than one point at a time. In general, a k-step block method is a set of k multi-step formulas that simultaneously produce k approximate values ​​of the solution of the differential problem at k points on a chosen mesh.

The symposium brings together different scholars working with the numerical solution of different types of differential equations, by using block methods.

The main topics include the solution of:

  1. Initial value problems

  2. Boundary value problems

Delay, Functional and Dynamic Equations with Applications



Prof. Syed Abbas, School of Basic Sciences, IIT Mandi, India. Email:

Delays are natural in several physical and natural phenomena. In predator prey system, predator starts hunting after reaching a certain age. Similarly mixing of various liquids is not instantaneous, so delay arises naturally. It is a vast field which has huge applications ranging from science to engineering. In order to unify the discrete and continuous calculus, Stefan Hilger's introduced a new theory which is called time scale. A time scale is any closed subset of real line, so apart from discrete and continuous, it covers other equations defined over quantum set, Cantor set etc. Although it has certain limitation, but in general this theory avoids double analysis for several system. The symposium brings together mathematicians, and engineers working with the qualitative theory of delay differential equations and dynamic equations on time scale.


The main topics include:
  1. Dynamic equation on time scale

  2. Delay differential equations

  3. Bifurcation analysis

  4. Stability analysis

  5. Applications in mathematical biology

Modelling and Simulation of Flow and Transport Processes in Porous Media



Prof . G. P. Raja Sekhar, Department of Mathematics, Indian Institute of Technology Kharagpur, India. Email:

Porous media are ubiquitous in various industrial and natural processes, and types of porous media range from subsurface application areas, contaminant hydrology, and petroleum engineering, to material science applications. In general, porous medium is everywhere from the brain to the fuel cell. Recently, there is a growing need of understanding and predicting the multiscale flow and transport phenomena in key energy and manufacturing sectors such as subsurface reservoirs, vadose and root zones, filtration, and nuclear reactors, CO2 sequestration, just to name a few. There are specific challenges in flow through porous media, such as heterogeneities at different scales, discontinuities in the medium characteristics and interface coupling etc. In addition, there are modelling difficulties with engineered porous media, such as complex evolving structures, non-stationary and non-equilibrium dynamics, ill-posed calibration and validation, coupling with multi-phase, thermal and mechanical processes. In order to tackle these challenges, researchers have been contributing significantly to develop robust modeling and numerical approaches to solve coupled systems of Partial Differential Equations in complex and heterogeneous domains. These include extensions of the classical analytical techniques, namely Volume Averaging and Two-scale Asymptotic Expansion; specific methods to tackle discontinuities, non-linearities; as well as numerical methods like Finite Elements and Finite Volumes, naturally well-suited for some of these challenges. In this mini symposium, we bring together Applied Mathematicians, Physicists, Petroleum, and Environmental Engineers, Hydro-geologists, to discuss the wider applicability and relevance of mathematical modeling and simulation techniques, and to transfer and bring new ideas into the traditional porous media community.

Many real-world problems are modelled by physically and mathematically interesting nonlinear systems of equations as well as nonlinear matrix equations which arise in different fields of science and engineering. Analytical methods are almost non-existent and limited to a selected class of problems. Therefore, iterative methods offer an attractive alternative to obtain the numerical solutions of these types of problems. Due to the recent development in computer algebra systems, numerical methods have gained much more attention than ever before due to their superior performances. Development and analysis of such methods are crucial to efficiently address these problems. The existence of an extensive literature on this topic reveals that it is a dynamic branch of the numerical analysis with interesting and promising applications.  This mini symposium aims at bringing together both theoreticians and practitioners to share recent advances in practical scientific problems, aiming to facilitate discussion and two-way dissemination of ideas across disciplinary and topical boundaries. We are interested in high-quality presentations that contain original research results.

Recent advances in computational science and parallel computing facilitates to solve largescale scientific and industrial problems. In particular, advancements in computing power enables to solve high-dimensional differential equations and to handle problems with big data. Consequently, it requires major changes in numerical algorithms and software design.
