Synecdoche

I have designed a cover for the book D-branes by Prof. Clifford Johnson. Why I did it? Because I was feeling sad that such a great book has such an uninteresting cover.

Both the conformal Stokes' theorem and the form of delta function δ(x) in complex space are given in page 119 of di Francesco (See equation 5.33 - 5.36). δ(x) = 1/π ∂ z' (1/z) where z is the complex coordinate. z = (x + i y) /2 & z' (z bar) = (x - i y) /2

Below is a code to customise search in Linux using find. find would recurse through all the directories. I needed to omit some directories which I knew didn't have the file I was looking for but instead have games. So recursing through them would cause enormous processor overhead and time loss. So I wrote a code in shell script to omit specific directories.. cd / for aa in `ls` do if [ "$aa" != "resident_evil" ] ; then if [ "$aa" != "usr1" ] ; then if [ "$aa" != "usr2" ] ; then if [ "$aa" != "usr3" ] ; then if [ "$aa" != "unreal" ] ; then if [ "$aa" != "quake3" ] ; then echo -e " Current search path: " cd $aa pwd find . -name "*.a" fi fi fi fi fi fi cd / done

While calculating T(z) T(w) OPE for bc ghosts and massless fermions I came across a weird result. I could get the central charge correct and also the T(w)/(z-w)^2 term correct but the other terms which remain does not add up to T(w) as expected. In massless fermion case: T = :ψ ∂ ψ: T(z) T(w) = 1/4/(z-w)^4 + T(w)/(z-w)^2 + ( 1/2 ψ ∂ 2 ψ + ∂ ψ ∂ ψ )/(z-w) But, ∂ T = ψ ∂ 2 ψ + ∂ ψ ∂ ψ So, I cannot account for the 1/2 factor in front of ψ ∂ 2 ψ . In bc ghost case : T = : 2 ∂ c b + c ∂ b : T(z) T(w) = 1/4/(z-w)^4 + T(w)/(z-w)^2 + ( 4 ∂ 2 c b + 3 ∂c ∂b - c ∂ 2 b)/(z-w) But, ∂T = 2 ∂ 2 c b + 3 ∂c ∂b + c ∂ 2 b This means I have some terms like T(z) T(w) = 1/4/(z-w)^4 + T(w)/(z-w)^2 + ( 4 ∂ 2 c b + 3 ∂c ∂b - c ∂ 2 b)/(z-w) = 1/4/(z-w)^4 + T(w)/(z-w)^2 + [∂ T + 2( ∂ 2 c b - c ∂ 2 b)]/(z-w) = 1/4/(z-w)^4 + T(w)/(z-w)^2 + ∂ [ T + 2 ( ∂c b - c ∂b) ]/(z-w) I have no idea why the term ( ∂c b - c ∂b) should be zero. So the problem is: 1. Whether it is correct to directly differe...

In linux it is very easy. Install CUPS-PDF and print to PDF. I explained it in another post previously. But sadly, if I follow this printing procedure the hyperlinks are not preserved in the resulting pdf file. So the alternatively we can use htmldoc to convert HTML to PDF. The command is - $ htmldoc lec.html --webpage -t pdf14 -f lec.pdf --webpage : turns on the webpage mode. -t : sets the output pdf type. -f : output filename. That's it. If you do not have htmldoc pre-install then install it with sudp apt-get install htmldoc in Ubuntu.

gr-qc/0512087v1 I read Petrov classification of 4 tensors and Serge classification of 2 tensors. Will it help my project on membrane paradigm? I don't know. But it is good to learn how a 4 tensor can be decomposed. I want to know more of this.

------ BOOTSPLASH --------- 1. http://www.64bitjungle.com/tag/boot-screen/ Usplash is the application that controls the boot splash, so I did a quick search in /etc for a conf file. Oddly enough, one exists, and it’s called usplash.conf . Running $ more /etc/usplash.conf # Usplash configuration file # These parameters will only apply after running update-initramfs. xres=1440 yres=900 2. I also edited the menu.lst file, in /boot/grub/ gksu gedit /boot/grub/menu.lst and changed the end of the “kernel” line for the default Linux image boot, removing “quiet”, and ensuring “splash” was also included: title Ubuntu 7.10, kernel 2.6.22-14-generic root (hd0,6) kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=[Your UUID] ro splash initrd /boot/initrd.img-2.6.22-14-generic 3. Restore splash screen from Kubutu to ubuntu To get back your familiar Ubuntu usplash image and screen $sudo update-alternatives --config usplash-artwork.so $ sudo dpkg-reconfigure usplash update-initramfs: Generating /boot/i...

http://www.devdaily.com/blog/post/latex/use-strikeout-strikethrough-font-with-latex Include the "ulem" package in the header like this. \documentclass[a4paper,12pt]{article} \usepackage{amssymb} \usepackage{hyperref} \usepackage{amsmath} \usepackage{ulem} % to use a strikeout/strikethrough font Then to produce strikeout use the command \sout{ ... } like this. \sout{Windows} Ubuntu rules. This produces output text like this: Windows Ubuntu rules. \sout command only works in text mode. To use strikeout in equations a different command should be used. Inside math mode the command \text{\sout{\ensuremath{ ... }}} should be used. Like this, \begin{eqnarray} \text{\sout{\ensuremath{R^{bc} = R^{00} + R^{BC} }}} \end{eqnarray}

The latest djvu viewer which is djview 4.4 allows the djvu file to be directly exported to pdf format. Just select File -> Export as ... -> Format: ( Destination ) PDF Document. But I fopund out that this didn't quite work in my system. After 99% of conversion was finished I kept getting the error message " Cannot render image. This operation failed ..." . So I went for the alternative. I printed the document using CUPS-PDF driver. Selec print and then PDF from the list of printers available. If PDF printer is not installed then you have to install it. Follow the guideline here http://www.ubuntugeek.com/how-to-create-pdf-documents-in-ubuntu.html or better still if you are using Debian then just open your PMS (package management system ;) Synaptic for Ubuntu ) and install "cups-pdf" .
