Re: Philosophy of Mathematics

Complex Number Theory without Imaginary Number (i)  by Code At the risk of being churlish, Euler's formula is called Eluer's formula several times in the text.  However, if some of you check the math and it is all rigorously correct, that is arguably more important. Perhaps you were hinting at that...

Re: LIBOR transition

2012. But the misbehavior is believed to have dated back to the early 1990s. The whole thing is reaching the level of mythology at this point: The Twelve, nay, The Thirteen Labors of Hercules 1) Slay the Nemean lion. 2) Slay the nine-headed Lernaean Hydra. 3) Capture the Ceryneian Hind. 4) Capture t...

Re: Philosophy of Mathematics

should math be read from left to right or from right to left, or read from the direction the math makes most sense, stay inside the other existing rules? one can easily set up nonorthodox equations that are wrong if read wrong direction, so there must be direction rules?  almost any language have r...

Re: Test your veggie skills

Nice!

And broccoli is full of fractals.

How many types of broccoli are there, roughly, and one Latin name?

Allium cepa? Red wing onion

Trying to think of a calculation involving onions.

Re: Good things that come out of this pandemic...

In essence I suppose good babies are like good models: fit for purpose, robust, taking in data and conveying information about the world.

looking at the music video - these fully mature examples must have been very good babies - strongly kicking and working at communication!

Re: Good things that come out of this pandemic...

Maybe see it in terms of the law of comparative advantage. Some are best suited to writing books. Some are best suited to having children. Some can actually manage to do both, under special conditions. Arguably, writing a really good book is even more difficult than producing a really good baby, mea...

Re: What are the typical assumptions for quant models for each asset class and what distortions do they produce?

Great - that is a very nice exposition. For the beginners/younger students, I will just lay out the key assumptions/issues with Black Scholes. Noted the thread where some you were going deeper into the terminology and the math, which is also a good exercise, but really it's the breaks on assumptions...

Re: What are the typical assumptions for quant models for each asset class and what distortions do they produce?

A good idea for this FAQ, but would be a textbook, and I doubt you'll get a taker at this point in time. To narrow the scope, if there's a troublesome assumption you can't find relaxed/fixed by diligent googling, post a question and maybe somebody will have an answer. To kick things off, I'd say th...
