A multiphase eigenvalue problem on a stratified Lie groupChoudhuri, Debajyoti (Avtor) Tavares, Leandro S. (Avtor) Repovš, Dušan (Avtor) multiphase spectral problemstratified Lie groupHeisenberg groupleft invariant vector field(2q)-eigenvalue problemWe consider a multiphase spectral problem on a stratified Lie group. We prove the existence of an eigenfunction of $(2, q)$-eigenvalue problem on a bounded domain. Furthermore, we also establish a Pohozaev-like identity corresponding to the problem on the Heisenberg group.20242024-11-15 12:06:13Članek v reviji164898UDK: 517.9ISSN pri članku: 0009-725XDOI: 10.1007/s12215-024-01035-1COBISS_ID: 195977219sl
