Abstract: Using SDSS-DR4 we studied the spatial distribution and the influence over star formation activity due to interactions in low and high surface brightness galaxies in the redshift range 0.01< z <0.1. With cylinder counts and projected distance to the fifth-nearest neighbor as environment tracers, we found that LSBs tend to have a lack of companions compared to HSBs in small scales (< 2 Mpc). Regarding the interactions, we found that the fraction of LSBs with strong star formation activity increases when the neighbor is closer than rp / r904. The intensity of the reaction, measured by the average value of b, seems to be stronger for HSBs compared to LSBs. Our results suggest that, rather than be a condition for their survival and evolution, isolation of LSBs is connected with their formation scenario.
