In this paper, space�time fractional three-field Kaup�Boussinesq equations with Riemann�Liouville fractional derivative are studied for invariant analysis. Symmetries are obtained by using classical Lie�s symmetry approach. Using obtained symmetries, the governing equations reduce to system of fractional ordinary differential equations which contains left and right-sided Erde� lyi- Kober (EK) fractional operators. � 2021, Springer Nature Singapore Pte Ltd.en-USEK operatorsLie�s symmetry analysisRiemann�Liouville fractional derivativeSpace�time fractional three-field Kaup�Boussinesq equationsConference paperhttp://link.springer.com/10.1007/978-981-15-5414-8_28
