+<br>We examine potential constraints from cosmic shear on the dark matter particle mass, assuming all darkish matter is made up of gentle thermal relic particles. Given the theoretical uncertainties involved in making cosmological predictions in such warm darkish matter eventualities we use analytical suits to linear heat dark matter power spectra and evaluate (i) the halo model using a mass operate evaluated from these linear energy spectra and (ii) an analytical fit to the non-linear evolution of the linear [garden power shears](http://bwiki.dirkmeyer.info/index.php?title=The_11_Best_Hair_Scissors_For_Expert-Level_Trims_And_Cuts) spectra. We optimistically ignore the competing effect of baryons for this work. We find strategy (ii) to be conservative in comparison with approach (i). We consider cosmological constraints utilizing these strategies,  [orchard maintenance tool](http://global.gwangju.ac.kr/bbs/board.php?bo_table=g0101&wr_id=1078628) marginalising over four different cosmological parameters. Using the more conservative technique we discover that a Euclid-like weak lensing survey along with constraints from the Planck cosmic microwave background mission major anisotropies might obtain a decrease restrict on the particle mass of 2.5 keV.<br>
