Abstract.The aim of this paper, is to investigate and characterizes the $ (\alpha,\beta)-(m_X,m_Y)$-contra continuous and $ (\alpha,\beta)-(m_X,m_Y)$ contra semi continuous functions. Also we introduce and investigate the $\alpha\beta-(m_X,m_Y)$ irresolute functions and $\alpha\beta-(m_X,m_Y)$ contra irresolute functions, some characterizations are obtained and some applications are shown.
