Drive permission problem

Image
0 Re-installed Ubuntu 18.04.1 LTS, keeping the old drive partitions (/media/user/drive1 and /media/user/drive2). Given permission to current user with " $sudo chown -R user:user /media/user/drive1 " after successful installation. Now some softwares not getting permission to open files from the drive. For eg: cannot open .aup file in audacity, showing 'permission denied to this drive' etc... Kindly provide a solution. -Jay permissions mount share | improve this question edited Jan 15 at 11:12 Jayapramod a

Backward Kolmogorov equation for simple markov process

Image
2 $begingroup$ The following exercise is from a course on SDE's and I am a bit stumped. Consider the process. $dX_t=lambdaleft(xi-X_t right)dt+gammasqrt{|X_t|}dB_t$ $lambda,xi,gamma>0$ Find $mathbb{P}^{X_t=x}left( X_t>2right)$ . Now I would start by finding transition probabilities $p(trightarrow T,xrightarrow X_T)$ in the backwards kolmogorov equation $frac{partial p}{partial t }+Lp=0$ , where $L$ is the generator for the diffusion. How would I then find the relevant area in the state space? And how to find the solution to the kolmogorov equation for these parameters? probability-theory stochastic-processes stochastic-calculus markov-process sde share | cite | improve this question
