Let F be a family of functions meromorphic in a domain D,let n≥2 be a positive integer,and let a≠0,b be two finite complex numbers.If,for each f ∈F,all of wh
We study the existence and non-existence of bound states(i.e.,solutions in W1,p(RN)) for a class of quasilinear scalar field equations of the form-△pu+V(x)|u|p
In this work,we mainly investigate the problem of complexity for a topologically dynamical system(X,f).We prove that f has a full measure center if there exists a countable base {Ui}∞i=0 of X satisfyi
