Description
Nonstandard Methods in Functional Anal..In the early 1960s, by using techniques from the model theory of first order logic, Robinson gave a rigorous formulation and extension of Leibniz' infinitesimal calculus. Since then, the methodology has found applications in a wide spectrum of areas in mathematics, with particular success in the probability theory and functional analysis. In the latter, fruitful results were produced with Luxemburg's invention of the nonstandard hull construction.

Since then, the methodology has found applications in a wide spectrum of areas in mathematics, with particular success in the probability theory and functional analysis. In the latter, fruitful results were produced with Luxemburg's invention of the nonstandard hull construction. However, there is still no publication of a coherent and self-contained treatment of functional analysis using methods from nonstandard analysis. This publication aims to fill this gap.Shipping Notes

Works Great!
Color: Black/Battery
I've only used it a few times since it arrived and it works great. Much better than the hand cranking can opener I've been using. It's a little loud, but that's not enough of a deterrent for me to stop using it. The noise is a temporary annoyance that I'll gladly put up with to have a can opener that actually completely opens a can.

Super convenient and easy to use!
Color: Black/Battery
This electric can opener is a game-changer in the kitchen. It operates smoothly with just the press of a button and leaves safe, smooth edges on the cans. Very compact and handy.

Injured finger from use
Color: Black/Battery
Just used the product for the first time today. Beware, it does work but it cut my daughter’s finger open really bad because it made the edge of the can stringy and she cut her finger on it. Be careful.

I'm almost 80 years old and have slight arthritis in my hands making it hard to open cans but this opener has been wonderful. So easy to use. Great purchase!!
