It is shown that the Clar number can be arbitrarily larger than the cardinality of a maximal alternating set. In particular, a maximal alternating set of a hexagonal system need n...
In this paper, the homotopy analysis method (HAM) is applied to solve a parameterized sixth order boundary value problem which, for large parameter values, cannot be solved by oth...
In this paper, we present an impulsive version of Filippov's Theorem for fractional differential inclusions of the form: D y(t) F(t, y(t)), a.e. t J\{t1, . . . , tm}, (1,...
