Schubert varieties are subvarieties of the flag variety F‘n(C), a smooth complex
projective variety consisting of sequences of sublinear subspaces of an n-dimensional
complex vector space, ordered by inclusion. They are ...
Economic recession has become a global and reccurring phenomenon which poses
worrisome uncertainties on assets’ returns in financial markets. Various stochastic
models have been formulated in response to price instability ...
The dynamics of the stock market indices log-returns (∆(lnS~t)) have been characterised by non-normal features such as upward and downward jumps of different
measures, asymmetric and leptokurtic features. The Bi-Power ...
The concept of stability in differential equations is of immense importance particularly for determination of properties of solutions of nonlinear equations which
cannot be readily solved to obtain closed analytic solutions. ...
Brinkman-Forchheimer Equations (BFE) are used to describe non-Darcy be havior of uid ow in a saturated porous medium. Researchers in this area have
focused on the study of structural stability and long time behavior of ...
Co-infection with malaria often complicate and increase the severity of disease
pathogenesis. The co-infection of malaria and Lassa fever has not been fully
understood. Many researcher have worked on mathematical models ...
The problems of pricing and hedging in nancial market are fundamental because of
uncertainties in the market which are measured by the sensitivities of the underlying
assets. Ito calculus has been used to develop several ...
Interest Rate Derivatives (IRDs) are generally jump-diffusion processes which
are usually modelled with L´evy processes. Brownian motion has been used ex tensively for modelling IRDs, however, this does not capture the ...
A sensitive investor seeks to diversify assets and optimal portfolio which provide
the maximum expected returns at a given level of risk. Optimal portfolio problems
of an investor with logarithmic utility have been ...
Nonlinear parabolic interface problems are frequently encountered in the modelling
of physical processes which involved two or more materials with di erent properties.
Research had focused largely on solving linear ...
