In this paper. we show the relationship between (skew) deductive system and (skew) filter in residuated skew lattices. It is shown that if a residuated skew lattice is conormal. then any skew deductive system is a skew filter under a condition and deductive system and skew deductive system are equivalent under some conditions too. https://www.hindigyanvishv.com/flash-deal-Iowa-Cubs-Foam-Finger-p32059-hot-value/
