[1] Janeček has authored and co-authored several research articles in scientific journals in the area of applied stochastic calculus, where his work has numerous citations,[1] such as "Optimal investment with high-watermark performance fee," SIAM Journal on Control and Optimization, 2012; "Futures trading with transaction costs," Illinois Journal of Mathematics, 2010; "Asymptotic analysis for optimal investment and consumption with transaction costs," Finance and Stochastics, 2004; and others.
