\textit{Definition 1.} Suppose that ... Then ... is called ...
\smallskip
Let ${\mathcal{H}}$ be a separable Hilbert space.
Suppose that $B$, $C$ and $D$ are bounded linear operators on ${\mathcal{H}}$,
$B$ and $C$ are symmetric and nonnegative ...

\textbf{Some other subsection.}
Usually expressing the $C_0$-semigroup $\left(e^{tL}\right)_{t\geq 0}$ it terms of variable coefficients of operator $L$ is a hard problem. However, if the so-called Chernoff function is constructed ...

%Please use explicit numeration of formulas using eqno command instead,
%as it is shown in (1). This will make each text self-contained.
