Extremal solutions for certain type of fractional differential equations with maxima Rabha W Ibrahim Institute of Mathematical Sciences University Malaya 50603 Kuala Lumpur Malaysia Email address rabhaibrahim@ Abstract In this article we employ the Tarski s fixed point theorem to establish the existence of extremal solutions for fractional differential equations with maxima. 1 Introduction Fractional calculus has become an exciting new mathematical method of solution of diverse problems in mathematics science and engineering. Indeed recent advances of fractional calculus are dominated by modern examples of applications in differential and integral equations 1 and .
