An alternative approach to solving the Black-Scholes equation with time-varying parameters
In this note we provide a simple derivation of an explicit formula for the price of an option on a dividend-paying equity when the parameters in the Black

New bounds for the Cebysev functional
Some new inequalities for the Cebysev functional in terms of the first derivative and applications for Taylor's expansion and generalised trapezoid formula are pointed out.

On the pseudo-inverse of the Laplacian of a bipartite graph
1 We provide an efficient method to calculate the pseudo-inverse of the Laplacian of a bipartite graph, which is2 based on the pseudo-inverse of the normalized Laplacian.3

Exact lower bound for proportion of maximally embedded beamlet
We prove that the maximal inscribed beamlet is at least 1/7 of an arbitrary line segment (i.e., beam). The implication of this result is addressed.

Well-posedness for a nonsmooth acoustic system
We consider an acoustic wave system with discontinuous coe cients and nonsmooth inputs. Existence, uniqueness and continuous dependence on input data of weak solutions are establi...
