We study Lp-theory of second order elliptic divergence type operators with measurable coefficients. To this end, we introduce a new method of constructing positive C0-semigroups on Lp associated with sesquilinear (not necessarily sectorial) forms in L2. A precise condition ensuring that the elliptic operator is associated with a quasi-contractive C0-semigroup on Lp is established.

Health inequalities often result from social inequities, and those, in turn, are generated by social determinants of health (SDoH). Hence, to reduce health inequalities, it is necessary to consider all health-related determinants. Disadvantages arise even before birth, and they tend to accumulate throughout an individual's life. Thus, policy actions intended to overcome these health inequalitie...
