 Nov24 asked Expectation of exponential martingale and indicator function. Nov23 comment Is it true that $X(t)^a > K \iff X(t) > K^\frac1a$ @Berci Yes. $\phantom{.}$ Nov23 accepted Is it true that $X(t)^a > K \iff X(t) > K^\frac1a$ Nov23 asked Is it true that $X(t)^a > K \iff X(t) > K^\frac1a$ Nov23 accepted Partial derivative notation: $\left.\frac{\partial \cdot}{\partial\cdot} \right|_{u=T}$ Nov22 comment Partial derivative notation: $\left.\frac{\partial \cdot}{\partial\cdot} \right|_{u=T}$ For the first question, why couldn't he have done $\frac{\partial B(t,T)}{\partial T}$, instead of using $u$ and then substituting in $T$ afterwards? Nov22 accepted Partial derivative of a summation. Nov22 asked Partial derivative notation: $\left.\frac{\partial \cdot}{\partial\cdot} \right|_{u=T}$ Nov22 revised Partial derivative of integral: Leibniz rule? added 26 characters in body Nov22 comment Partial derivative of integral: Leibniz rule? @joriki What I meant was whether you could apply it in the way that littleO applied it. Since you can do so, the answer to my question is yes. I've edited for disambiguation. Thanks. Nov22 accepted Partial derivative of integral: Leibniz rule? Nov21 comment Partial derivative of integral: Leibniz rule? @joriki the provided answer seems to suggest that the same formula does hold. Nov21 asked Partial derivative of integral: Leibniz rule? Nov15 comment Integral with respect to Wiener process. @GautamShenoy Ok well I guess I've done 2 calculus/analysis subjects and 1 linear algebra, forgot the first 1 I did. It's in a finance undergraduate degree, they decided to chuck in a quantitative finance course which is all stochastic calculus with a lil measure theory and probability theory. Nov15 comment Integral with respect to Wiener process. @GautamShenoy What I meant to ask was for you to provide some additional hints - in mathematics. I probably should've couched this in different language. I've done 1 calculus and 1 linear algebra subject at University. Nov15 comment Integral with respect to Wiener process. @GautamShenoy I'm afraid that this does not assist me given my current understanding of mathematics. I don't think I can use the second fundamental theorem because i just have $d$ instead of $\frac{d}{dt}$ preceding the integral. Nov15 asked Integral with respect to Wiener process. Nov15 asked Partial derivative of a summation. Nov10 accepted Integration of Wiener process: $\int_{t_1}^{t_2} dB(s)$ Nov10 comment What is $57^{46}$ divided by 17? This answer is hilarious!
