Regularity for minimizers for functionals of double phase with variable exponents

MA Ragusa, A Tachikawa - Advances in Nonlinear Analysis, 2019‏ - degruyter.com
The functionals of double phase type H (u):=∫| D u| p+ a (x)| D u| qdx,(q> p> 1, a (x)≥ 0) are
introduced in the epoch-making paper by Colombo-Mingione for constants p and q, and …

Double phase transonic flow problems with variable growth: nonlinear patterns and stationary waves

A Bahrouni, VD Rădulescu, DD Repovš - Nonlinearity, 2019‏ - iopscience.iop.org
In this paper we are concerned with a class of double phase energy functionals arising in
the theory of transonic flows. Their main feature is that the associated Euler equation is …
