The logo on the right is the arabic letters of the word Algorithmi (al-Khwarizmi) the persian muslim scholar after him algorithms and logarithms were named
It still takes a few seconds to identify the word since this is not how Arabic is usually written but yes the word "Al-Khawarizmi" is legible.
In fact, the logo contains text both in black and navy blue, the navy blue part is "Al-Khawarizmi" or in Arabic "الخوارزمي". Then the navy blue script is rotated at 90 degrees 3 additional times.
Logo on the right of what? All I see is a geometric design in the middle of the cover. It doesn't look Arabic and it seems like it would be very cumbersome for someone to sign as a name.
I remember tracing the lines with my finger as a kid, trying to decipher a hidden logic...
