- What is the meaning of infinitesimal? - Mathematics Stack Exchange
Likewise, Infinitesimal is a concept; its value is smaller than any value you can imagine Check out this video and you will appreciate why Infinity and Infinitesimal cannot be "explained" to someone seeking to find "applications" "methodology"
- ordinary differential equations - What is the Lie group infinitesimal . . .
Our prof gave us the definition of the Lie group infinitesimal generator and it's kth-coordinate, he also explained why the kth-coordinate is called "the kth-coordinate", but nonetheless he didn't want to explain the Lie group infinitesimal generator because "we will understand it later as the course will continue"
- How do you understand Infinitesimals? - Mathematics Stack Exchange
While it is possible to create number systems with infinitesimals, that does not validate the intuition that you've stated, that somehow $0 \overline{9}$ and $1$ differ by an infinitesimal You lose a lot of nice properties of the real numbers when you add infinitesimals
- Are infinitesimals equal to zero? - Mathematics Stack Exchange
Hence, zero is also an infinitesimal But not necessarily exactly like other infinitesimals, because it seems you cannot add zero to itself any number of times and arrive to anything other than zero, while you can add other infinitesimals to themselves and arrive to real values
- Definition of an Infinitesimal - Mathematics Stack Exchange
That chapter defines: A number $\epsilon$ is said to be infinitely small, infinitesimal, if: $-a < \epsilon < a$ And goes on to an introduction to the hyperreal line However, this definition seems to imply an infinitely small number ($\epsilon$) is one which is between $\pm a$, which seems to be a very large range if you choose, for example
- Whats an example of an infinitesimal? - Mathematics Stack Exchange
Cauchy said that a sequence converging to zero becomes an infinitesimal rather than is an infinitesimal The idea that he meant a null sequence to generate an infinitesimal is confirmed by the fact that he was interested in rates of growth of sequences and even tried to classify those
- calculus - infinity times infinitesimal - what happens? - Mathematics . . .
In non-standard analysis, an infinitesimal times an infinite number can have various values, depending on their relative sizes The product can be an ordinary real number But it can also be infinitesimal, or infinite Similarly, the ratio of two "infinite" objects in a non-standard model of analysis can be an ordinary real number, but need not be
- probability - Infinitesimal generator : what is it exactly . . .
Infinitesimal generator of Brownian motion with additional jumps 0 Proving that drift-less Geometric
