Energy estimate for wave equations with coefficients in some Besov type class. <i>Electronic Journal of Differential Equations, 2007</i>(85), pp. 1-12.1072-6691https://hdl.handle.net/10877/14280In this paper, we obtain an energy estimate for wave equations with coefficients satisfying Besov type conditions. We give an example of a wave equation with continuous and nowhere differentiable coefficients for which the L2 estimate holds.Text12 pages1 file (.pdf)enAttribution 4.0 InternationalWave equationEnergy estimateNon regular coefficientsArticle
