Comparison of Boundary Value Problems,llowing simple result for second order equations motivates our study. Consider the second order equation . with . > 0. Here ... = ... = .′ and . = 1 is the only admissible integer. The conjugate point bvp, in fact the (1,1)-conjugate bvp, is . and the focal point bvp issparse 发表于 2025-3-27 08:08:33
Solutions on an Infinite Interval,ation when its domain of definition ends with a singular point. For simplicity we shall consider the interval [.,∞), however, similar results hold on an interval [.,ω), when the equation has a suitable singularity at . and solutions may oscillate on [.,.).Glycogen 发表于 2025-3-27 12:31:40
Disconjugacy and its Characterization,s characterization serves as a basis to a large number of necessary conditions and sufficient conditions for (.)-disfocality. For (.)-disconjugacy the situation is quite different. Our study is less systematic and each result is proved by some ad hoc method.把手 发表于 2025-3-27 13:47:06

Disfocality and its Characterization,Among all boundary value functions, the (.)-focal point is most easily treated thanks to the characterization of (.)-disfocality by a naturally arising set of inequalities.
