## Ram U. Verma, Semiinfinite multiobjective fractional programming problems using exponential type generalized invexities, Volume 2017, Number 3, Pages 16-33, 2017

Abstract: In this paper, first a class of second order exponential type hybrid $(\alpha$, $\beta$, $\gamma$, $\eta$, $\rho$, $h(\cdot,\cdot)$, $\kappa(\cdot,\cdot)$, $\omega(\cdot,\cdot,\cdot)$, $\varpi(\cdot,\cdot,\cdot)$, $\theta)$-invexities is introduced, and then a class of parametrically sufficient efficiency conditions based on the second order exponential type hybrid invexities is established....
