| Abstract | It was shown in Björn–Björn–Korte [5] that u := min{u1, u2} is a Q-quasisuperminimizer if u1 and u2 are Q-quasisuperminimizers and Q = 2Q2/(Q+1). Moreover, one-dimensional examples therein show that Q is close to optimal. In this paper we give similar examples in higher dimensions. The case when u1 and u2 have different quasisuperminimizing constants is considered as well. |
