Discover what a log-normal distribution is, its financial applications, and how to calculate it, including using Excel for ...

For example, if you are calculating a stock option based on the Black-Sholes model, you will need the natural logarithm function "LN" in Excel, the normal distribution, "NORM.DIST" and the "EXP ...

Logarithmic convexity type continuous dependence results for discrete harmonic functions defined as solutions of the standard $C^0$ piecewise-linear approximation to Laplace's equation are proved.

When the logarithmic function is approximated by sequences of algebraic functions, similar questions can be posed as in the case of other similar problems. So, for example, it is interesting to ...
