湛江師范學(xué)院青年項(xiàng)目(QL1021)

全衛(wèi)貞(1980- )，女，廣西玉林人，講師，碩士，研究方向：差分方程與動(dòng)力系統(tǒng)

近些年來(lái)，差分方程理論引起了許多學(xué)者、專家的重視，已成為現(xiàn)代數(shù)學(xué)的一個(gè)研究熱點(diǎn)．Ladas等人在文獻(xiàn)[1]中提出了關(guān)于差分方程的公開問題和猜想；另外，差分方程的奇點(diǎn)集和解的有界性、收斂性、穩(wěn)定性、周期性等動(dòng)力學(xué)性質(zhì)也得到了人們的廣泛關(guān)注，并獲得很多的研究成果[1-12]．
