Abstract: In the paper we introduce an idea of harmonic functions with correlated coefficients which generalize the ideas of harmonic functions with negative coefficients introduced by Silverman and harmonic functions with varying coefficients defined by Jahangiri…

Abstract: Time-series image change detection is one of the most challenging tasks to remote sensing society. Due to complex phenological patterns of cropland, it is difficult to design an efficient strategy for cropland change detection. In…

Abstract: We prove that in Minkowski spaces, a harmonic function does not necessarily satisfy the mean value formula. Conversely, we also show that a function satisfying the mean value formula is not necessarily a harmonic function.…
