Biharmonic continuations of gradients with the help of monogenic functions with values in the biharmonic algebra
UDC 517.5 Necessary and sufficient conditions are established for the existence of the continuations of gradients of biharmonic functions $u_1$ and $u_2$ across a smooth curve $\Gamma$ ($u_k \colon D_k \longrightarrow \mathbb{R},$ $k=1,2,$ and $\Gamma$ is a common part of the boundaries of $D_1$ and...

Necessary and sufficient conditions are established for the existence of the continuations of gradients of biharmonic functions $u_1$ and $u_2$ across a smooth curve $\Gamma$ ($u_k \colon D_k \longrightarrow \mathbb{R},$ $k=1,2,$ and $\Gamma$ is a common part of the boundaries of $D_1$ and $D_2$). Moreover, the indicated  continuation of gradients determines the gradient of the biharmonic function (in $D_1 \cup \Gamma \cup D_1$). |
