Upper bounds for systoles on punctured surfaces If the systole is defined as the length of the shortest essential simple closed curve are there any known upper bounds for hyperbolic surfaces with punctures?
 A: Yes, since the injectivity radius (defined as the max of injectivity radii over all points of the surface) is bounded by roughly the log of the area (think "embedded disk"). For interesting papers on this subject, check out:
